r600g/radeonsi: send endian info to format translation functions

Because r600 GPUs can't do swap in their DB unit, we need to disable
endianess swapping for textures that are handled by DB.

There are four format translation functions in r600g driver:

- r600_translate_texformat
- r600_colorformat_endian_swap
- r600_translate_colorformat
- r600_translate_colorswap

This patch adds a new parameters to those functions, called
"do_endian_swap". When running in a big-endian machine, the calling
functions will check whether the texture/color is handled by DB -
"rtex->is_depth && !rtex->is_flushing_texture" - and if so, they will
send FALSE through this parameter. Otherwise, they will send TRUE.

The translation functions, in specific cases, will look at this parameter
and configure the swapping accordingly.

v4:
evergreen_init_color_surface_rat() is only used by compute and don't
handle DB surfaces, so just sent hard-coded FALSE to translation
functions when called by it.
