drm/xe/bmg: Apply Wa_22019338487
Extend this WA to BMG GT as well. In this case media GT is
not affected. The cap frequencies and max allowed ggtt writes
are different as well. On BMG, we need to do a flush after 1100
GGTT writes, and we need to limit the GT frequency request
to 2133 Mhz during driver load and leave it at that value after
driver unloads.
