gpu: nova-core: add FbHal::frts_size() for GA100 support

Browse source 
Introduce FbHal method frts_size() to return the size of the FRTS
window.  GA100 is a special case in that although there is an
FRTS, its size must arbitrarily be set to 0.

Note that we cannot use supports_display() to determine the FRTS
size because there are other GPUs (e.g. GA102GL) that have display
disabled (and so supports_display() returns False), but the FRTS
window size still needs to be 1MB.
