[PATCH v9 03/23] gpu: nova-core: gsp: Return GspStaticInfo from boot()

[Joel Fernandes <joelagnelf@nvidia.com>]

Refactor the GSP boot function to return only the GspStaticInfo,
removing the FbLayout from the return tuple.

This enables access required for memory management initialization to:
- bar1_pde_base: BAR1 page directory base.
- bar2_pde_base: BAR2 page directory base.
- usable memory regions in vidmem.
