zink/ci: move zink+$DRV from zink to $DRV config
It makes more sense to me to keep all the settings about a driver in the same location.
All the lines are moved verbatim, except Combined testing (GL, GLES, Piglit) on RADV
in the zink config that I changed to Combined testing (GL, GLES, Piglit) on Zink+RADV
when I moved it to the radv config, and the include
in zink/ci/gitlab-ci.yml
that I removed when I folded zink/ci/gitlab-ci-inc.yml
into the otherwise empty zink/ci/gitlab-ci.yml
.
