libpayload/arm64: Round fb_size up to a multiple of GRANULE_SIZE
If a framebuffer is already configured by coreboot, we need to ensure
that the framebuffer size is a multiple of GRANULE_SIZE before passing
to `mmu_add_memrange`. Otherwise, we would fail to allocate memory
region due to `sanity_check`.
