Subject: i965/blorp: Cleanup leftovers from push constant disabling
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7d29fee4a8c5648bdd7b3af45ad1e38b0a058a0e;p=mesa.git

i965/blorp: Cleanup leftovers from push constant disabling

Setup for pixel shader push constants is the same as for other
stages. Note that on gen8+ the if-else branches were identical
and the generation check for packet size redundant.
