On STM32WL, the backup memory is defined as part of the TAMP peripheral.
This seems to be a deviation from the stm32 family where this memory is
defined as part of the RTC.
The STM32WL reference manual shows that tamp_pclk is connected to
rtc_pclk. This means that the clock required to run the TAMP peripheral
is the same as the RTC's. A quick port of BBRAM on STM32WL is achieved
by instanciating the bbram device as a child of the RTC and by modifying
the address offset to the first backup register from the rtc base
address.

When enabling async RX the first time after boot, there is an
additional byte received with the first RX_DATA_RDY event,
which seems to be caused by the RX data not being flushed before
enabling the UART RX DMA.
Adding a request to flush the RX data register before enabling
the RX DMA, solves the issue.

Do not enable subsystem/driver shell modules by default and stop abusing
CONFIG_SHELL_MINIMAL, which is internal to the shell subsystem, to decide
when to enable a driver shell.
The list of shell modules has grown considerably through the
years. Enabling CONFIG_SHELL for doing e.g. an interactive debug session
leads to a large number of shell modules also being enabled unless
explicitly disabled, which again leads to non-negligible increases in
RAM/ROM usage.
This commit attempts to establish a policy of subsystem/driver shell
modules being disabled by default, requiring the user/application to
explicitly enable only those needed.

This commit introduces the SOF host DMA driver.
This driver is used by NXP platforms in the context of
SOF's host component to copy data from the host memory
to the firmware (local) memory. This is possible because
NXP platforms can access the host memory directly w/o
an actual DMA engine.

This moves the k_* memory management functions from sys/ into

functions are further separated into the kernel internal
header directory.
Also made a quick change to doxygen to group sys_mem_* into

At present, if you want to set a periodic timer again with
set_top_value, the last triggered event is not cleared. This could
result in an old event being served at the next interrupt activation.
The solution proposed in this patch adds the nrf_timer_event_clear
function into set_top_value to prevent this from happening in the
above case.

Interrupt-driven mode was not working, and disabled by default.
When it was forced on, the behavior was to only have a few bytes:
as many as min(CONFIG_SHELL_BACKEND_SERIAL_TX_RING_BUFFER_SIZE, 9).
After the hardware FIFO was filled by software and emptied by hardware,
no interrupt occured, and enqueuing more data did never happen.
By letting the events enabled for TX (only), then interrupts are still
generated after the first transfer, and the software can then add the
subsequent transfers until all data is print: the UART works.
It does not generate endless interrupts either, which was tested by
adding litex_write8('%', UART_RXTX_ADDR) in liteuart_uart_irq_handler()
to log all interrupts events, and when there is nothing to print, no
interrupt is fired.
It was tested with the Zephyr shell.

This commit implements this enhancement:
https://github.com/zephyrproject-rtos/zephyr/issues/63018
The forms of the gpio commands are now:
gpio conf device pin ol0
gpio set device pin 1
gpio get device pin
gpio blink device pin
Device name and pin subcommands now are
suggested/completed when tab is used.
Pin names are suggested with numbers and line names if
available from the gpio controller’s Devicetree node.
GPIO pin command is now limited to pins that are not assigned
as reserved.
