Eric Anholt 2cc7a0815e glamor: Drop the GLES2 REVERT_UPLOADING_2_10_10_10 paths. 
These just smash your 2_10_10_10 data into 8888, despite what the
comments said.  That's not valid rendering, so just ditch this path
and fall back to software.  One might also note in the code being
removed here that the REVERT_UPLOADING_10_10_10_2 path wasn't even
connected.
