This reverts commit ebc8c6f18322ad54275997a888ca1731d74b711f. There are still missing corner cases with cursor interaction and these fast plane updates on Picasso and Raven2 leading to endless PSTATE warnings for typical desktop usage depending on the userspace. This change should be reverted until these issues have been resolved. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110949Signed-off-by:

[Why] After clkmgr rework it gets initialized after resource pool. The clkmgr is used in resource pool init for xgmi path. That causes driver crash on Vega20 with xgmi due to NULL deref.
