[Mesa-dev] [PATCH] i965/icl: Don't set float blend optimization bit in CACHE_MODE_SS

[Anuj Phogat]

CACHE_MODE_SS is not listed in gfxspecs table for user mode
non-privileged registers. So, making any changes from Mesa
will do nothing. Kernel is already setting this bit in
CACHE_MODE_SS register which is saved/restored to/from
the HW context image.
