_mesa_choose_tex_format() already handles GL_RGBA + GL_UNSIGNED_SHORT_1_5_5_5_REV by converting it to MESA_FORMAT_B5G5R5A1_UNORM. Teach it do the same for the non-reversed type. Otherwise, the switch's fallthrough converts it to an 8888 format, which has incompatible precision in the alpha channel.
Patch 2/2 to fix dEQP-EGL.functional.image.modify.tex_rgb5_a1_tex_subimage_rgba8 on Intel.
