Generates x86 and arm firmware bitmap blocks.

X86 (coreboot) uses 800x600 resolution while ARM systems (uboot) initialze LCD
as its maximum size, so we must refine the bmpblk build scripts to generate
output with different scaling parameters.

BUG=chrome-os-partner:11078
TEST=make # got ARM bmpblock and verified to work on daisy.
