rk3399: Reserve enough framebuffer memory for 32bpp hires panels
Some of our RK3399 devices have panel resolutions as high as 2400x1600. With 16bpp that barely still fit into an 8MB framebuffer, but then we changed it to 32bpp for better image quality...
Note that this is a band-aid. Coreboot-allocated framebuffers shouldn't be used at all on ARM64 devices, since libpayload is perfectly capable to dynamically allocate it with the right size based on EDID-information on this architecture. That will require some more elaborate work to be fixed with later patches.
BRANCH=gru BUG=chrome-os-partner:58044 TEST=Warm-reboot Kevin on the dev screen, confirm that you don't see the lower half of the screen that overflowed our allocated framebuffer preserved from the last boot as soon as the backlight turns on.
