Add a new API used by arch to implement suspend-to-RAM (S2RAM).
The API is composed by a single function to save the CPU context on
suspend.
A CPU context is the arch-specific set of registers that must be
preserved on power-off (in retained RAM) to be able to resume the
execution from the point it was suspended without going through the
whole kernel startup stage.

Now that we have 8 bits reserved for vendor specific GPIO flags,
introduce a new set of flags for nRF platforms to configure pins drive
mode. These new flags are equivalent to the previous existing ones, but
use a naming scheme the fits better with vendor hardware capabilities.
The table below shows the equivalence between old and new flag
| Old flags | New flags |
|---------------------------|-----------------------|
| `NRF_GPIO_DS_DFLT_LOW` | `NRF_GPIO_DRIVE_S0` |
| `NRF_GPIO_DS_DFLT_HIGH` | `NRF_GPIO_DRIVE_S1` |
| `NRF_GPIO_DS_ALT_LOW` | `NRF_GPIO_DRIVE_H0` |
| `NRF_GPIO_DS_ALT_HIGH` | `NRF_GPIO_DRIVE_H1` |
| `NRF_GPIO_DS_DFLT` | `NRF_GPIO_DRIVE_S0S1` |
| `NRF_GPIO_DS_ALT` | `NRF_GPIO_DRIVE_H0H1` |
| `NRF_GPIO_DS_DFLT_LOW \|` | `NRF_GPIO_DRIVE_S0H1` |
| `NRF_GPIO_DS_ALT_HIGH` | |
| `NRF_GPIO_DS_ALT_LOW \|` | `NRF_GPIO_DRIVE_H0S1` |
| `NRF_GPIO_DS_DFLT_HIGH` | |
Documentation has been written to explain in more detail the meaning of
the flags and how they can be used.

Fix missing recv fifo reset on HCI reset. This fix handles a
scenario where in Rx Prio thread has enqueued a node rx, Tx

rx post HCI Reset Command handled in Tx thread.

This adds the bits to allow the process thread to notify
backends when it has finished processing pending log messages.
This allows, for example, flash-based backends to group writing
log messages to storage to limit wear, since log_output_flush()
is called per message. Also the backend does not have to resort
to using timer to periodically flush its buffer to storage,
avoiding waking up the device when there are no messages.
Another use of this is for backends requiring DMA transfers.
Grouping all pending log messages into one DMA transfer is
sometimes preferrable.

The thingy53_nrf5340 board definition based on the nrf5340dk_nrf5340

In commit 619a498845, the initialization
of the spi2 node has been moved from the nrf5340_cpuapp_common.dts file
to separate dts files for secure/non-secure targets. That was done
to make the node unavailable in the nRF5340 PDK, that was also using
the common file, because it was non-functional on that board.
For the same reason, the initialization of the usbd node could not
be done in the common file and instead it had to be added separately
for the secure and non-secure targets.
Now that the nRF5340 PDK is no longer supported, there is no point in
keeping such complication. The usbd node initialization is moved to the
common file but the spi2 node initialization is removed and instead the
spi4 node is enabled, as it is labeled as arduino_spi and is assigned
with the same pins.
