drm/xe/wopcm: fix WOPCM size for LNL+

Starting on LNL the WOPCM size is 8MB instead of 4, so we need to avoid
using the [0, 8MB) range of the GGTT as that can be unaccessible from
the microcontrollers.

Note that the proper long-term fix here is to read the WOPCM size from
the HW, but that is a more serious rework that would be difficult to
backport, so we can do that as a follow-up.
