drm/amd/display: Revert "init dispclk from bootup clock for DCN315"
[ Upstream commit a625dc4989a2affb8f06e7b418bf30e1474b99c1 ]
[Why&How]
This reverts commit 14bb17cc37e0.
Due to the change, the display shows garbage on startup.
We have an alternative solution for the original issue:
d24203bb629f ("drm/amd/display: Re-check seamless boot can be enabled or not")
