r600g: port color buffer format conversion from radeonsi
r600_translate_colorformat is rewritten to look like radeonsi. r600_translate_colorswap is shared with radeonsi. r600_colorformat_endian_swap is consolidated. This adds some formats which were missing. Future "plain" formats will automatically be supported. Cc: [email protected] Reviewed-by: Alex Deucher <[email protected]>
