drm/i915/perf: Do not parse context image for HSW
An earlier commit introduced a mechanism to parse the context image to
find the OA context control offset. This resulted in an NPD on haswell
when gem_context was passed into i915_perf_open_ioctl params. Haswell
does not support logical ring contexts, so ensure that the context image
is parsed only for platforms with logical ring contexts and also
validate lrc_reg_state.
v2: Fix build failure
v3: Fix checkpatch error
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/7432
Fixes: a5c3a3cbf029 ("drm/i915/perf: Determine gen12 oa ctx offset at runtime")
