gpu: nova-core: gsp: Extract and display usable FB regions from GSP

Browse source

Add usable_fb_regions() to GspStaticConfigInfo to extract the usable FB
regions from GSP's fbRegionInfoParams. Usable regions are those that are
not reserved or protected.

The extracted regions are stored in GetGspStaticInfoReply and exposed
for use by the memory subsystem.

Display the regions and their total size upon device probe.

[acourbot: expose all regions as a KVec, display usable regions and
total usable VRAM.]
