mesa st: Change the preferred internal format for some RGB formats.
For GL_RGB5, GL_RGB4 and GL_R3_G3_B2, prefer PIPE_FORMAT_R5G6B5_UNORM over PIPE_FORMAT_A1R5G5B5_UNORM, since hardware is more likely to support the previous format for rendering. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>
