New GuC 32.0.3 firmware made many changes around its ABI that require driver updates:
* FW release version numbering schema now includes patch number * FW release version encoding in CSS header * Boot parameters * Suspend/resume protocol * Sample-forcewake command * Additional Data Structures (ADS) This commit is a squash of patches 3-8 from series [1].
