Targets without the `errno` module enabled will not render `OSError`s
with the name of the error. Instead they just print the numeric error
code.
Add support for such targets by explicitly recognising certain error codes.

will enable XSPI memory-mapped mode before jumping to the application
firmware in the external SPI flash.

This commit adds preliminary support for ST's new STM32N6xx MCUs.
Supported features of this MCU so far are:
- basic clock tree initialisation, running at 800MHz
- fully working USB
- XSPI in memory-mapped mode
- machine.Pin
- machine.UART
- RTC and deepsleep support
- SD card
- filesystem
- ROMFS
- WiFi and BLE via cyw43-driver (SDIO backend)
Note that the N6 does not have internal flash, and has some tricky boot
sequence, so using a custom bootloader (mboot) is almost a necessity.

That's almost the same as FLT_EVAL_METHOD == 0, but indicates the
presence of _Float16_t support.

This is useful for interfaces that stay in memory-mapped mode by default.
They can implement this method with a simple `memcpy()`.

Attempting to configure SPI3 and SPI4 for the STM32H5 would fail with a
linker error. This patch resolves that, ensuring that appropriate DMA
channels are assigned to those SPI resources.

On STM32H5/STM32H7, SPI flash cannot use as storage device with DMA. SPI
interruption may not be genearated even if DMA transfer has been done.
This is due to lower priority of SPI interruption than DMA.
This commit changes SPI interrupt priority more higher than DMA's priority.

This tests that the RXIDLE callback is called correctly after a second lot

On stm32, the hardware generates an RXIDLE IRQ after enabling the UART,
because the RX line is technically idle.
Signed-off-by: Damien George <damien@micropython.org>
These MCUs only clear the RX idle IRQ if the data register is read, which
won't occur if the only IRQ is the RX idle IRQ (because then reading and
discarding the DR may lead to lost data).
To work around this, explicitly suppress the RX idle IRQ so that it's only
passed through to the Python callback once.

Some targets like frdm_k64f don't support GPIO_OUTPUT|GPIO_INPUT, so just
use GPIO_OUTPUT in those cases (it seems they still support reading the
current output state even when configured only as GPIO_OUTPUT, unlike other
targets which require both settings).

Although the rpi_pico can already build and run with the zephyr port, this
configuration improves it in a number of ways:
- Use the USB CDC ACM as the REPL, rather than just a UART.
- Enable I2C and SPI, and add I2C1.
- Enable a filesystem, which matches exactly the rp2 port's RPI_PICO
configuration. So switching between zephyr and rp2 is possible and will
retain the filesystem.
- Make the MicroPython GC heap make the most use of the available RAM.

Bluetooth works well now on this board, so enable all supported features.
Also increase the MicroPython GC heap size to make use of the available
RAM.
Unfortunately the filesystem does not match the stm32 port's NUCLEO_WB55
configuration. That's not possible to do because stm32 uses a 512 byte
flash erase size, while zephyr uses 4096 bytes. But at least here in
zephyr there's now a sizable and usable filesystem.

Support for importing .mpy files is quite fundamental to MicroPython these
days, eg it allows installing more efficient .mpy code via "mip install"
(and installing `unittest` only works with the .mpy version because the .py
version uses f-strings, which are not enabled on the zephyr port). So
enable it generally for use by all boards.
As part of this, also enable:
- min/max: needed by `micropython/import_mpy_invalid.py`, and widely used
- sys.modules: needed by `run-tests.py` to run .mpy tests with --via-mpy
- io module: needed to run .mpy tests, and useful for `io.IOBase`
- array slice assign: needed to run .mpy tests, and generally useful as a
way to do a memory copy.

There are two changes here:
1. Increase the UART input bufffer to 512 bytes. That's necessary to get
basic REPL reliability tests working, and helps improve `mpremote`
usage, eg copying large files.
2. Remove `uart_sem` semaphore. This is no longer needed because
`zephyr_getchar()` should be fully non-blocking and have as low a
latency as possible. `mp_hal_stdin_rx_chr()` (which calls
`zephyr_getchar`) already uses `MICROPY_EVENT_POLL_HOOK` to get
an efficient wait, and doing an extra wait and check for the
semaphore in `zephyr_getchar()` just introduces unnecessary latency and
can lead to slower input, and potentially overflowing the UART input
buffer.

This change enables `sys.stdin`, `sys.stdout` and `sys.stderr` objects.
They are useful for general IO, and also help with testing zephyr boards.
