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 extende

After the new config option is merged we'll enable it by default in the
CI config, but for now just force it on via the i915 Kconfig so we can
get pre-merge CI results for it.

Some platforms require the host to poll on the
GSC registers instead of relaying on the interrupts.
For those platforms, irq initialization should be skipped

Define GSC on XeHP SDV (Intel(R) dGPU without display)
XeHP SDV uses the same hardware settings as DG1, but uses polling
instead of interrupts and runs the firmware in slow pace due to
hardware limitations.

A work-around for a HW issue in XEHPSDV that manifests itself when SW reads
a gsc register when gsc is sending an interrupt. The work-around is
to disable interrupts and to use polling instead.

GSC requires more operational memory than available on chip.
Reserve 4M of LMEM for GSC operation. The memory is provided to the
GSC as struct resource to the auxiliary data of the child device.

Each LFP may have different panel type which is stored in LFP data
data block. Based on the child device index respective panel-type/
panel-type2 field will be used.
v1: Initial rfc verion.
v2: Based on review comments from Jani,
- Used panel-type instead addition panel-index variable.
