Subject: i915: Remove a bunch of default handling of pipe caps.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eb7642c53d09a245c3907a40e31013ee19a2e043;p=mesa.git

i915: Remove a bunch of default handling of pipe caps.

u_screen will return 0 for all of these, which means that this is one
less driver to see in git grep when I'm checking who exposes a cap.
The exception is the texel/gather offsets and stream output
components, which will not be exposed since we don't expose the
corresponding GLSL version.
