[PATCH 01/26] drm/i915/tgl/perf: use the same oa ctx_id format as icl

[Timo Aaltonen]

From: Michel Thierry <michel.thierry at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1871957

Compared to Icelake, Tigerlake's MAX_CONTEXT_HW_ID is smaller by one, but
since we just use the upper 32 bits of the lrc_desc, it's guaranteed OA
will use the correct one.
