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.

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

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.
