gpu: nova-core: compute layout of the FRTS region
FWSEC-FRTS is run with the desired address of the FRTS region as
parameter, which we need to compute depending on some hardware
parameters.
Do this in a `FbLayout` structure, that will be later extended to
describe more memory regions used to boot the GSP.
