msm: camera: csiphy: Handle process shutdown during secure camera

Browse Source 
Use SCM 7 call during the process shutdown. This is to
workaround a race condition between the close of camera FD
and the invoke driver FD that leads to a device crash.
Additionally, keep the Domain ID clocks on only during
protect or unprotect operations.
