From: Tilak Tangudu <tilak.tangudu@xxxxxxxxx>
1. Added D3Cold-Off support for runtime pm for discrete gpu.
2. LMEM is switched off and gpu is in off state in D3Cold-Off
so, lmem & GT deep suspend/resume is added.
3. Re-used i915_gem_backup_suspend, i915_gem_suspend_late
and i915_gem_resume to handle above 2.
4. These functions use runtime helpers, which in-turn call
runtime suspend/resume callbacks and leads to deadlock.
So, these helpers need to be avoided.
5. Added is_intel_rpm_allowed and disallowed rpm callbacks
during suspending and resuming.
6. Integrated D3Cold policy patch, but is a FIXME, as LMEM
usage is not queried, lmem->avail stopped tracking lmem
usage after ttm port.
7. Added/used i915_save/load_pci_state helpers
8. In intel_guc_global_policies_update, guarded intel_guc_is_ready
with rpm helpers as it needs guc interaction.
9. Fixed error *ERROR DC state mismatch (0x8 -> 0x0)".
10. Guarded rc6 rpm helpers with is_intel_rpm_allowed as these
are called in suspend/resume cllbacks.
