drivers: stm32_remoteproc: Add remote processor memories cleanup function

This patch introduces a new function stm32_rproc_clean_up_memories() to
clean up the memory regions used by the remote processor.
The function iterates over each memory region, maps it, clears the memory
by setting it to zero, and then unmaps it.

drivers: stm32_rif: add stm32_rif_access_violation_action()

This function should be used by peripherals capable on raising
access violation interrupts (SERC, IAC). The behavior of the platform
on such event is platform-specific. Therefore, its definition must be
done at platform level.

Also add CFG_STM32_PANIC_ON_IAC_EVENT and CFG_STM32_PANIC_ON_SERC_EVENT
to choose if the platform should panic upon receiving an IAC or a
SERC event.

core: kernel: Fix checking register convention r1/x1 value of transfer_list

According to recently firmware handsoff spec [1]'s
"Register usage at handoff boundary", Transfer List's signature value
was changed from 0x40_b10b (3 bytes) to 4a0f_b10b (4 bytes).

As updating of TL's signature, register value of x1/r1 should be:

In aarch32's r1 value should be
R1[23:0]: set to the TL signature (4a0f_b10b->masked value: 0f_b10b)
R1[31:24]: version of the register convention == 1
and
In aarch64's x1 value should be
X1[31:0]: set to the TL signature (4a0f_b10b)
X1[39:32]: version of the register convention == 1
X1[63:40]: MBZ
(See the [2] and [3]).

Therefore, it requires to separate mask and shift value for register
convention version field when checking each r1/x1 value.

This patch fix two problems:
1. breaking X1 value with updated specification in aarch64
- change of length of signature field.

2. previous error value set in R1 in arm32.
- length of signature should be 24, but it uses 32bit signature.

This patch is a breaking change. It works only TF-A is updated.

core: kernel: dt_driver: fix nodes reference passed in dt_pargs

Correct the DT node references passed in struct dt_pargs. Field
phandle_node is expected to be the node offset of the provider driver
but dt_driver_device_from_node_idx_prop_phandle() implementation passes
node offset -1, dt_driver_device_from_parent() passes the consumer
node offset and dt_driver_device_from_node_idx_prop() may pass the
phandle node offset from a previous index in the parsed DT node property.

Fix that by adding field consumer_node to reference the node offset of
the consumer device and fixing phandle_node where applicable and
update atmel_i2c and stm32_i2c drivers to get the I2C device address
from the consumer_node field instead of the phandle_node that is now
fixed.
