drivers: plic: Maintain controller data in driver source file

To align the design from other architecture, we move the interrupt
controller data instance from platform source file to driver source
file. With this change, the PLIC initialization functions no more get
the controller data as input argument. Platforms do not need to care
about the interrupt controller data instance.

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.

drivers: regulator framework

Introduces a voltage regulator driver framework for management
of regulators and supply dependencies. The framework permits 1
regulator supply per regulator.

API function regulator_register() allows a regulator driver to
register a regulator in the regulator framework.

Supported operation here are to enable, disable, get and set
voltage level. They are all optional.

Registered regulators are referenced in a list for initialization
resource release and debug purpose.

core: support fault mitigations in non-threaded code

Fault mitigation won't work in non-threaded code due to the following
error:
assertion 'ct >= 0 && ct < CFG_NUM_THREADS' failed at core/arch/arm/kernel
/thread.c:799 <thread_get_id>

The problem is in __ftmn_get_tsd_func_arg_pp which calls thread_get_tsd
which thread_get_id. The reason is that the interrupt handler is not
associated with any thread, so the ct (current_thread_id) value is -1 which
would cause an assert problem.

The fix is to add ftmn_arg to thread_core_local and the new variable would
be used when the current thread is < 0.
