drm/xe: Add Indirect Ring State support
...
When Indirect Ring State is enabled, the Ring Buffer state and
Batch Buffer state are context save/restored to/from Indirect
Ring State instead of the LRC. The Indirect Ring State is a 4K
page mapped in global GTT at a 4K aligned address. This address
is programmed in the INDIRECT_RING_STATE register of the
corresponding context's LRC.
v2: Fix kernel-doc, add bspec reference
v3: Fix typo in commit text

drm/xe: Remove dependency on intel_lrc_reg.h
...
Create regs/xe_lrc_layout.h file with all the offsets used by the xe
driver. Eventually the xe driver may use a different way to define them
since it doesn't supported below gen12.
v2: Rename file to intel_lrc_layout.h since it's not really about
registers (Matt Roper)
