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

Greg KH, please review and ACK the MEI patches.
We are pushing these patches through gfx tree as
the auxiliary device belongs there.

V2: rebase over merged DG1 series and DG2 enablement patch,
    fix commit messages

V3: rebase over latest tip
