core: fix data abort during ftrace

With commit c10e3fa93d24 ("core: fix race in handling TA panic") the
resources of a panicked TAs are released as early as possible, including
the user space mapped ftrace buffer. However, the pointer to the ftrace
buffer is stored in the ts_session for quick and easy access. The ftrace
buffer is always retrieved with get_fbuf() that already have a few other
checks to see if the buffer is currently available. So add a check to
see that the TA hasn't panicked also.

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.
