Add GSC support for XeHP SDV and DG2 platforms. The series includes changes for the mei driver: - add ability to use polling instead of interrupts - add ability to use extended timeouts - setup extended operational memory for GSC The series includes changes for the i915 driver: - allocate extended operational memory for GSC - GSC on XeHP SDV offsets and definitions - GSC on DG2 offsets and definitions The first six patches of the series are copied from the already reviewed series [1] to provide series that can be built in CI. This series will be rebased and merged only after series [1] merge. Greg KH, please review and ACK the MEI patches. We are pushing these patches through gfx tree as the auxiliary device belongs there.
