bitmap: Draw a bitmap in reverse from the right y offset.

When drawing a bitmap from the top row down, we should start at y + height - 1
instead of y + height.

BUG=chrome-os-partner:19420
TEST=Built for pit and booted into recovery mode and then switched to dev mode.
Saw that the bitmap no longer overwrote part of the coreboot tables by
overflowing the end of the framebuffer by one line.
BRANCH=None
