OMAP: Fix race condition with autodeps
There is a possible race condition in clockdomain
code handling hw supported idle transitions.
When multiple autodeps dependencies are being added
or removed, a transition of still remaining dependent
powerdomain can result in false readings of the
state counter. This is especially fatal for off mode
state counter, as it could result in a driver not
noticing a context loss.
Fixed by disabling hw supported state transitions
when autodeps are being changed.
