59b7166d87 stm32: Add initial support for STM32WBxx MCUs.
This new series of MCUs is similar to the L4 series with an additional
Cortex-M0 coprocessor.  The firmware for the wireless stack must be managed
separately and MicroPython does not currently interface to it.  Supported
features so far include: RTC, UART, USB, internal flash filesystem.

e1ae9939ac stm32: Support compiling with object representation D.
With this and previous patches the stm32 port can now be compiled using
object representation D (nan boxing).  Note that native code and frozen mpy
files with float constants are currently not supported with this object
representation.

cb3456ddfe stm32: Don't use %lu or %lx for formatting, use just %u or %x.
On this 32-bit arch there's no need to use the long version of the format
specifier.  It's only there to appease the compiler which checks the type
of the args passed to printf.  Removing the "l" saves a bit of code space.

a03e6c1e05 stm32/irq: Define IRQ priorities directly as encoded hardware values.
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART).  Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority.  This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.

For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.

This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).

e37b8ba5a5 stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc.  Prefer
to use these instead of custom ones.

3eb0694b97 stm32: Update HAL macro and constant names to use newer versions.
Newer versions of the HAL use names which are cleaner and more
self-consistent amongst the HAL itself.  This patch switches to use those
names in most places so it is easier to update the HAL in the future.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
