[Intel-xe] [PATCH] drm/xe: Fix wopcm size

[Balasubramani Vivekanandan]

The wopcm size returned by xe_wopcm_size function is used in calculating
the GuC wopcm base offset and the GuC wopcm size. It is also used to
find the size of the wopcm space to be reserved at the bottom of the
GGTT address space. So it is the per-GT wopcm size and not the total
wopcm area used by all GTs.
Fix the wopcm size to 2MB which is the wopcm size per-GT for platforms
above Gen11.
