[PATCH v2 01/15] drm/xe/xe3p_lpg: Add support for graphics IP 35.10

[Gustavo Sousa <gustavo.sousa@intel.com>]

From: Shekhar Chauhan <shekhar.chauhan@intel.com>

Add Xe3p_LPG graphics IP version 35.10. Xe3p_LPG supports all features
described by XE2_GFX_FEATURES and also multi-queue feature on BCS and
CCS engines.  As such, create a new struct xe_graphics_desc named
graphics_xe3p_lpg that inherits from XE2_GFX_FEATURES and also includes
the necessary .multi_queue_engine_class_mask.

Here is a list of fields and associated Bspec references for the members
of the IP descriptor:

 .hw_engine_mask (Bspec 60149)
 .multi_queue_engine_class_mask (Bspec 74110)
 .has_asid (Bspec 71132)
 .has_atomic_enable_pte_bit (Bspec 59510, 74675)
 .has_indirect_ring_state (Bspec 67296)
 .has_range_tlb_inval (Bspec 71126)
 .has_usm (Bspec 59651)
 .has_64bit_timestamp (Bspec 60318)

v2:
  - Drop non-existing fields from the list in the commit message. (Matt)
  - Squash patch adding .multi_queue_engine_class_mask here. (Matt)
  - Rename graphics_xe3p to graphics_xe3p_lpg. (Matt)
