Re: [PATCH v9 04/23] gpu: nova-core: gsp: Extract usable FB region from GSP

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

The extracted region is stored in GetGspStaticInfoReply and exposed via
usable_fb_region() API for use by the memory subsystem.

This doesn't take into account the feedback I gave in [1]. In
particular, a TODO to handle the remaining regions looks important to
me.
