  To: intel-xe; +Cc: matthew.d.roper, tejas.upadhyay

Add GT workaround Wa_14026578760 for graphics versions 35.10, 35.11
and media version 35.03.

Signed-off-by: Varun Gupta <varun.gupta@intel.com>

v4:
 - Drop separate media register define; MEDIA_GT_GSI_OFFSET is applied
   automatically by the media GT's mmio, so a single XE_REG_MCR
   suffices for both graphics and media (Matt Roper)
v3:
 - Use separate register defines for graphics and media (Tejas)
v2:
 - Fix register define ordering (Matt Roper)
 - Broaden workaround scope to cover graphics 35.10, 35.11 and media
   35.03 per workaround database (Matt Roper)
