drivers: wdt: add SMC handler for arm-smc-wdt Linux driver

Add SMC handler to handle SMC coming from Linux arm-smc-wdt driver.
This function is meant to be called in sm_platform_handler() since
CFG_WDT_SM_HANDLER_ID is going to be defined by the platforms.

plat-sam: pm: add support for setting suspend mode

PSCI allows entering platform suspend with SYSTEM_SUSPEND call which
is meant to enter the system in its deepest power state. sama5d2
platform supports multiple suspend power states. Currently, Linux
supports the atmel.pm_modes command line option which allows to select
this suspend state. Since Linux uses PSCI SYSTEM_SUSPEND to enter
suspend mode, we are not able to pass information (such as done for
CPU_SUSPEND). In order to select the mode that will be entered by
SYSTEM_SUSPEND from normal world and thus select the desired suspend state,
SMCs are added to allow selecting and getting this power mode.

drivers: caam: instantiate RNG state handle with prediction resistance

Instantiate RNG state handles with Prediction Resistance (PR) support.
This way SW further downstream (e.g. Rich OS, boot loader etc.) is able
to use the "PR" bit in RNG generation descriptors (forcing TRNG
re-seeding before PRNG / DRBG outputs random data).

Note: current patch does not deal with RNG state handles that have
already been initialized, but without PR support (this could happen if
U-boot would run before OP-TEE etc.). In this case, RNG state handle
would have to be deinstantiated first, and then reinstantiated with
PR support.

Implementing these changes required a fix in the Plug-and-Trust tree
(the addition of a missing dependency), therefore we will also bump
the Plug-and-Trust version used in the Azure pipeline.
