[Intel-gfx] [PATCH xf86-video-intel 1/6] sna: Add SAMPLER_OFFSET() compile time asserts for gen6/7

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

gen8/9 has some compile time asserts to verify the SAMPLER_OFFSET() bits
don't exceed their quota of the flags. Add similar asserts for gen6/7.
