[PATCH i-g-t v8 0/6] Compression support for Lunarlake

[Akshata Jahagirdar <akshata.jahagirdar@intel.com>]

Series enables the compression feature for Lunarlake and address various
changes of the feature from Gen12. The Main-to-CCS ratio has been
changed to 512:1. This changes the calculations and value for fields
such as CCS Copy size for blitter command APIs. 
This patch series updates tests xe_ccs and gem_ccs for XE2.
This series doesn't solve "in-place" and "suspend-resume" subtests.

These changes are based on top of the "vm_bind pat_index" patch here:
