Umesh Nerlige RamappaandGreg Kroah-Hartman 3f16340071 drm/xe: Save CTX_TIMESTAMP mmio value instead of LRC value ...

[ Upstream commit 66c8f7b435 ]

For determining actual job execution time, save the current value of the
CTX_TIMESTAMP register rather than the value saved in LRC since the
current register value is the closest to the start time of the job.

v2: Define MI_STORE_REGISTER_MEM to fix compile error
v3: Place MI_STORE_REGISTER_MEM sorted by MI_INSTR (Lucas)
