[PATCH v3 0/2] drm/xe:Mutual exclusivity between CCS-mode and PF

[Nareshkumar Gollakoti <naresh.kumar.g@intel.com>]

Due to SLA agreement between PF and VFs, Currently we block CCS mode
changes if driver is running as PF, even if there are no VFs enabled yet.
Use lockdown mechanism provided by the PF to relax that limitation
and still enforce above VFs related requirements.Also skipping CCS-mode
sysfs entry in VF Mode.
