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).
NOTE: the FW team has asked to not send the current FW blob to
linux-firmware yet, as they're planning some updates. Therefore, the
FW definition patch will have to be merged to the topic/core-for-CI
branch for now and moved to gt-next once the FW is ready.
v2: fix header parsing, address other minor review comments.
