Revert "ANDROID: PM / Domains: add vendor_hook to disallow domain idle state"

Browse Source 
This reverts commit e114871401.

The hook is not used by any vendor, so remove it to help with merge
issues with future LTS releases.

If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.
