Last chunk of the required support for the GSC FW. This includes some
fixes to the GSC memory allocation, FW idefinition and version
management, plus a new debugfs for debug information.

Adding the FW definition will enable all the features that are dependent
on the GSC being loaded (Media C6, HuC loading, SW proxy, PXP, HDCP).

The HuC series [1] has been included, squashed in a single patch,
as one of the patches in this series depends on it, but it should be
reviewd in its own thread.
