[Mesa-dev] [PATCH] i965: Add RGBX8888 and RGBA8888 to EGL configure and reorder the list

[Randy Xu]

On Android platform, the EGL configuration query (eglGetConfigs) will
check the DRI backend. Add R8G8B8A8 and R8G8B8X8 to meet the native app
test requirement (like gl2_basic etc.).

Reorder the list and move the B5G6R5 to the tail, it can solve two dEQP
failures on Android platform, they are dEQP-GLES3.functional.fragment_ops.
blend.default_framebuffer.rgb_func_alpha_func.src.dst_color_one_minus_dst_alpha
& .dst_color_constant_alpha. These two failures are all caused by B5G6R5 low
precision and the dEQP case always choose the first EGL configure id in list
returned by eglGetConfigs. The failure cannot be reproduced on X11 platform as
Intel does not support 16bit visuals with X driver
