Adds support for asynchronous notifications via FF-A with SPMC at S-EL1.

The OP-TEE FF-A ABI is extended to report support for asynchronous
notifications during OPTEE_FFA_EXCHANGE_CAPABILITIES.

The SPMC at S-EL1 is extended to provide the FF-A notifications ABI to a
normal world VM.

The notifications depends on having a non-secure SGI interrupt ID
available to notify normal world that a notification is pending.
Notifications becomes available once platform code has called
thread_spmc_set_async_notif_intid() with a designed SGI ID.

Regulator instances may not be created and initialized when

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.
