[Mesa-dev] [PATCH 03/12] isl/gen7: remove unneeded ISL_DEV_GEN check

From: Emil Velikov <emil.velikov at collabora.com>

The function gen7_format_needs_valign2 has two callers - the gen7 only
gen7_choose_valign_el() and isl_gen6_filter_tiling(). The latter of
which already guarding the invocation appropriately.

To be extra cautious add a couple of asserts alongside the removal of the
runtime check.

With this done the only runtime check (and even slightly different code
in general) is in isl_gen6_filter_tiling(). We might want to rework that
alike isl_surface_state.c or split it to per GEN vfuncs... at some point
