11ef8f22fe py/map: Add an optional cache of (map+index) to speed up map lookups.
The existing inline bytecode caching optimisation, selected by
MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE, reserves an extra byte in the
bytecode after certain opcodes, which at runtime stores a map index of the
likely location of this field when looking up the qstr.  This scheme is
incompatible with bytecode-in-ROM, and doesn't work with native generated
code.  It also stores bytecode in .mpy files which is of a different format
to when the feature is disabled, making generation of .mpy files more
complex.

This commit provides an alternative optimisation via an approach that adds
a global cache for map offsets, then all mp_map_lookup operations use it.
It's less precise than bytecode caching, but allows the cache to be
independent and external to the bytecode that is executing.  It also works
for the native emitter and adds a similar performance boost on top of the
gain already provided by the native emitter.

7b89ad8dbf py/vm: Add a fast path for LOAD_ATTR on instance types.
When the LOAD_ATTR opcode is executed there are quite a few different cases
that have to be handled, but the common case is accessing a member on an
instance type.  Typically, built-in types provide methods which is why this
is common.

Fortunately, for this specific case, if the member is found in the member
map then there's no further processing.

This optimisation does a relatively cheap check (type is instance) and then
forwards directly to the member map lookup, falling back to the regular
path if necessary.

01374d941f py/mpconfig.h: Define initial templates for "feature levels".
This is the beginning of a set of changes to simplify enabling/disabling
features.  The goals are:
- Remove redundancy from mpconfigport.h (never set a value to the default
  -- make it clear exactly what's being enabled).
- Improve consistency between ports.  All "similar" ports (i.e. approx same
  flash size) should get the same features.
- Simplify mpconfigport.h -- just get default/sensible options for the size
  of the port.
- Make it easy for defining constrained boards (e.g. STM32F0/L0), they can
  just set a lower level.

This commit makes a step towards this and defines the "core" level as the
current default feature set, and a "minimal" level to turn off everything.
And a few placeholder levels are added for where the other ports will
roughly land.

This is a no-op change for all ports.

0d7366c912 mimxrt: Rework flash configuration.
- Moves definition of BOARD_FLASH_SIZE and other header files related to
	flash configuration into the Makefile.
- Adds board specific clock_config.h.
- Adds board.h, pin_mux.h, and peripherals.h as they are
	required by NXP MCU SDK in order to use our own clock_config.h.
- Renames board specific FlexSPI configuration files.
- Updates flash frequency of MIMXRT1020_EVK
- Creates separated flash_config files for QSPI NOR and
	QSPI Hyper flash.
- Unifies VFS start address to be @ 1M for 1010 and 1020 boards.
- Unifies 1050EVK boards
- Adds support to both NOR and HyperFlash on boards with
	both capabilities.
- Adds automatic FlexRAM initialization to start-up code based on
	linker script and NXP HAL.
- Applies code formatting to all files in mimxrt port.

With this change the flash configuration is restructured and
organized. This simplifies the configuration process and
provides a better overview of each board's settings. With the integration
of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better
control of the settings and clock configurations. Furthermore the
implementation of an explicit FlexRAM setup improves the system
performance and allows for performance tuning.

e6850838cd py/parse: Simplify parse nodes representing a list.
This commit simplifies and optimises the parse tree in-memory
representation of lists of expressions, for tuples and lists, and when
tuples are used on the left-hand-side of assignments and within del
statements.  This reduces memory usage of the parse tree when such code is
compiled, and also reduces the size of the compiler.

For example, (1,) was previously the following parse tree:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=2)
          int(1)
          testlist_comp_3b(149) (n=1)
            NULL
      NULL

and with this commit is now:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=1)
          int(1)
      NULL

Similarly, (1, 2, 3) was previously:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=2)
          int(1)
          testlist_comp_3c(150) (n=2)
            int(2)
            int(3)
      NULL

and is now:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=3)
          int(1)
          int(2)
          int(3)

87f97e490c mimxrt/sdcard: Implement SDCard driver.
- Configures `PLL2->PFD0` with **198MHz** as base clock of
	`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
        to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!

SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.
