Pull LUNA's framebuffer improvements by Kenji Aoyama from OpenBSD/luna88k.

>> Use raster(logic) operation, or ROP, function on LUNA frame buffer.
>> It makes 4bpp wscons putchar ~20% faster.

This Makes 4bpp wscons putchar ~30% on LUNA-II.

Also use the similar ROP in 1bpp putchar and cursor functions
and the 1bpp putchar is also ~5% faster.
While here, reduce diffs from OpenBSD a bit.

Tested on all 1bpp/4bpp/8bpp framebuffers.
