[Mesa-stable] [PATCH 3/3] gallium/radeon: disable evergreen_do_fast_color_clear for BE

[Oded Gabbay]

This function is currently broken for BE. I assume it's because of
util_pack_color(). Until I fix this path, I prefer to disable it so users
would be able to see correct colors on their desktop and applications.

Together with the two following patches:
- gallium/r600: Don't let h/w do endian swap for colorformat
- gallium/radeon: remove separate BE path in r600_translate_colorswap

it fixes BZ#72877 and BZ#92039
