regulator: fix OF node imbalance on reuse

Johan Hovold <johan@kernel.org> says:

These drivers reuse the OF node of their parent multi-function device
but fail to take another reference to balance the one dropped by the
platform bus code when unbinding the MFD and deregistering the child
devices.

Fix this by using the intended helper for reusing OF nodes.

Note that the first two patches will cause a trivial conflict with Doug's
series adding accessor functions for struct device flags which has now been
merged to the driver-core tree:

ASoC: Fixes for v7.0

A somewhat larger set of fixes than I'd like unfortunatey, not from any
one place but rather spread out over different drivers. We've got a
bunch more fixes for the SDCA interrupt support, several relatively
minor SOF fixes, a few more driver specific fixes and a couple more AMD
quirks.

sched/debug: Fix avg_vruntime() usage

John reported that stress-ng-yield could make his machine unhappy and
managed to bisect it to commit b3d99f43c72b ("sched/fair: Fix
zero_vruntime tracking").

The commit in question changes avg_vruntime() from a function that is
a pure reader, to a function that updates variables. This turns an
unlocked sched/debug usage of this function from a minor mistake into
a data corruptor.

sched/fair: Increase weight bits for avg_vruntime

Due to the zero_vruntime patch, the deltas are now a lot smaller and
measurement with kernel-build and hackbench runs show about 45 bits
used.

This ensures avg_vruntime() tracks the full weight range, reducing
numerical artifacts in reweight and the like.

Also, lets keep the paranoid debug code around fow now.
