Pass sdhc_softc instead of sdhc_host to sc_vendor_transfer_data_dma,
since the vendor specific code has no access to it otherwise,
but can easily do device_private(sdhc_softc->sc_dev).

Pull readability changes from OpenBSD/luna88k.
- prepare and use unpack_attr() function to get fg and bg from attribute
- use proper variable names to clarify meanings
Tested on LUNA-II with 8bpp framebuffer.
Put dumb optimizations to avoid conditionals in putchar drawing loops.
~10% improvements of time cat results on LUNA-II 8bpp framebuffer.

> 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.

broke kwin for me.
