Deprecates gic_cpu_init() in favor of the new function
gic_init_per_cpu(). gic_cpu_init() is only supposed to be called by
secondary CPUs in non-TF-A configurations while gic_init_per_cpu()
should be called by all secondary CPUs. gic_init_per_cpu() itself takes
CFG_WITH_ARM_TRUSTED_FW into account instead of having each platform
doing that.

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.

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
