libpayload: Cache copy of `cb_framebuffer` struct
Our AArch64 code supports dynamic framebuffer allocation which makes it necessary to change the framebuffer information during runtime. Having a pointer inside `libsysinfo` made a mess of it as the pointer would either refer to the original struct inside the coreboot table or to a new struct inside payload space. The latter would be unaffected by a relocation of the payload. Instead of the pointer, we'll always keep a copy of the whole struct, which can be altered on demand without affecting the coreboot table. To align the `video/graphics` driver with the console driver, we also replace `fbaddr` with a macro `FB` that calls phys_to_virt().
