instead of update_texture_surface().
For gen < 7 this interface can be supported relatively easily
by changing the interface of brw_update_texture_surface().
I didn't switch BRW_SURFACE_LOD_SHIFT to be emitted using
SET_FIELD() as the mask for it is not defined yet. This can be
addressed as a simple follow-up.
Note also that the common dispatcher already considers the
texture buffer case and hence the corresponding calls in gen7
and gen8 dependent logic are redundant and are therefore safe
to drop.
Fixes piglit test arb_copy_image-formats on ILK as the minimun
layer is taken into account. Normally this isn't needed for
gen < 7 as those do not support GL_ARB_texture_view. However,
our meta path for 2D blits requires it regardless if the
extension is officially supported.
