5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

a0432ed9cb mimxrt: Update port to work with new nxp_driver v2.10.
The nxp_driver v2.10 allows for/requires some changes to the code:

- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
  library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI.  It's faster and interferes less with
  other modules.
- Use the clock_config.c files of library v2.8.5.  The mimxrt files keeps
  the clock_config.c files from Verson 2.8.5.  With clock_config.c from
  v2.10, the boards do not work.  Refactoring of the clock set-up is on the
  to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
  code.
- The clock_config.* files are moved from the board-specific directories to
  the boards directory and given a MCU related name.

c5dbbf71c0 mimxrt: Use -Og instead of -O0 for DEBUG builds.
Thanks for the hint, Damien. The DEBUG build got very large recently.
The major difference is, that inline function are now inlined and
not included as a function. That's good and maybe bad. The good thing is,
that the code speed si now close to the final code. It could be worse
in single step debugging. I'll see.

Setting this option caused a new warning and a formatting error
to pop up at different places. Fixed as well.

1e9eaa7af5 mimxrt: Add a driver for the DP83848 PHY device.
Just another choice for the PHY interface.

Added: Keyword option phy_clock=LAN.IN or LAN.OUT
to define the source of the 50MHZ clock for the PHY
interface. The RMII clock is not enabled if it
is generated by a PYH board. Constants:

LAN.IN  The clock is provided by the PHY board.
LAN.OUT The clock is provided by the MCU board.

The default is LAN.OUT or the value set in mpconfigboard.h, which
is currently set to IN only for the SEEED ARCH MIX board. Usage etc:

lan = LAN(phy_type=LAN.PHY_DP83848, phy_clock=LAN.IN)

1866ed7e2e mimxrt/eth: Add LAN support and integrate the network module.
This commit implements 10/100 Mbit Ethernet support in the mimxrt port.

The following boards are configured without ETH network:
- MIMXRT1010_EVK
- Teensy 4.0

The following boards are configured with ETH network:
- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK
- MIMXRT1064_EVK
- Teensy 4.1

Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.

Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works

The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.

Some boards do not wire the RESET and INT pin of the PHY transceiver.  For
operation, these are not required.  If they are defined, they will be used.
