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.

Encryption Key blob. It encapsulates and encrypts the plain text key used
to encrypt the boot image. This blob is decapsulated by the HAB - High
Assurance boot at boot to decrypt the boot image.

The DEK blob is a specific CAAM blob as it requires a header and the key
must be encapsulated from the CAAM secure memory.

core: fix race in handling TA panic

A TA context (struct tee_ta_ctx), can only be accessed and manipulated
if either locked or set to busy by the current thread, or if it has no
no other references.

Prior to this patch this wasn't followed by tee_ta_open_session(),
tee_ta_invoke_command(), and dump_ta_memstats(). Accesses were made to
the "panicked" field of struct tee_ta_ctx.
destroy_ta_ctx_from_session() was also manipulating sessions possibly
being used by other threads.

So fix this by only accessing the internals of the TA context while
holding the needed lock. destroy_ta_ctx_from_session() is removed, the
new ts_ops callback release_state() is used instead to free what can be
freed from a panicked TA context. The last session referencing the TA
context will free it.

core: add release_state to struct ts_ops

Adds the optional function pointer release_state() to struct ts_ops.
This callback will be called when a TA has panicked and as many
resources as possible need to be released early. release_state() is a
subset of the destroy() callback. When the destroy() is called
eventually it will free the entire state of the TA regardless if
release_state() has been called before or not. This allows freeing
resources while there are still open sessions to the TA.
