[PATCH v2 1/4] drm/xe/oa: Rename last argument of WHITELIST_OA_MMIO_TRG

[Ashutosh Dixit <ashutosh.dixit@intel.com>]

OA head pointer registers are not used by UMD's and do not need to be
whitelisted, the last argument of WHITELIST_OA_MMIO_TRG is actually used
for whitelisting tail pointer and OA buffer registers. Rename the argument
to tail_buf to reflect this. OA head pointer is sometimes provided to the
WHITELIST_OA_MMIO_TRG to have the correct register offset alignment (16)
for RING_FORCE_TO_NONPRIV_RANGE_4.

Fixes: ed455775c5a6 ("drm/xe/rtp: Refactor OAG MMIO trigger register whitelisting")
