Alexandre Courbot	80213934d0	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.

Alexandre Courbot	6554ad65b5	gpu: nova-core: register sysmem flush page ... Reserve a page of system memory so sysmembar can perform a read on it if a system write occurred since the last flush. Do this early as it can be required to e.g. reset the GPU falcons. Chipsets capabilities differ in that respect, so this commit also introduces the FB HAL.
