drm/msm/a6xx: Remove cx gdsc polling using 'reset'
Remove the unused 'reset' interface which was supposed to help to ensure
that cx gdsc has collapsed during gpu recovery. This is was not enabled
so far due to missing gpucc driver support. Similar functionality using
genpd framework will be implemented in the upcoming patch.
This effectively reverts commit 1f6cca404918
("drm/msm/a6xx: Ensure CX collapse during gpu recovery").
