plat-k3: drivers: Open TRNG firewall for TIFS

On devices with PLATFORM=k3-am62x, there is only one SA2UL instance,
which is being shared between TIFS and OP-TEE.

Blocking access to TRNG from all other entities other than OP-TEE
is causing firewall exception when being accessed by TIFS.

While there are other platforms with only one sa2ul instance, on AM62x
we support low power mode, in which TIFS access TRNG while waking up
from deep sleep. On other devices, use of TRNG by TIFS is limited to
the time till OP-TEE initializes and firewalls it for other entities.

Allow access to TIFS to use SA2UL TRNG along with OP-TEE.

core: ffa: preserve 64bit smccc when possible

Prior to this patch when a FFA_MSG_SEND_DIRECT_REQ_64 was received the
response was sent as FFA_MSG_SEND_DIRECT_RESP_32. While not breaking
with the FF-A specification, it's still a bit unexpected and will cause
an error in the FF-A framework driver. So fix this by keeping track of
the SMCCC (SMC Calling Convention) used during the current
FFA_MSG_SEND_DIRECT_REQ and respond with matching SMCCC.

This has no impact on AArch32 mode since only the 32-bit SMCCC is valid
in that case. The greatest impact on AArch64 is that we must be able to
find out the current SMCCC during RPC, this means storing it in struct
thread_core_local to be able to access it in assembly low level
routines.

Support for FFA_MSG_SEND_DIRECT_REQ_64 is also advertised in
FFA_FEATURES.

drivers: regulator: register to dt_driver

Adds regulator_dt_register() for regulator drivers to register
regulator instances based on the DT description of the platform.

Regulator instances may not be created and initialized when
regulator_dt_register() returns. When a regulator depends on a
supply this latter may not yet be registered and initialized.
The framework will resolve the regulator dependencies later.

At OP-TEE core last initcall stage, a debug message informs
in case of remaining unresolved regulator dependency. Used resources
are released and no error status is returns to the system.

regulator_dt_register() uses a dedicated struct regu_dt_desc
ABI to get the description of the regulator to be registered.
