drm/xe: Allow to exclude part of GGTT from allocations

Browse source

Soon we will be required to exclude some of the GGTT addresses
from the allocations, since on some platforms running the SR-IOV VF
mode, we will be able to use only selected range of the GGTT space.

Add helper functions to manage such GGTT range exclusions, and
follow the naming from the similar concept used by GVT-g.
