[Mesa-dev] [PATCH 08/10] r600g: set endianess of 16/32-bit buffers according to endian_format

[Oded Gabbay]

This patch modifies r600_colorformat_endian_swap(), so for 16-bit and for
32-bit buffers, the endianess configuration will be determined not only
by the color/texture format, but also by the resource's endian_format
value.

The only exception is for 8_8_8_8 formats, which are always set to
little-endian, because for them, gallium sets a different pipe_format
based on endianess
