media: coda: update profile and level controls after sequence initialization 

The header report return value from decoder sequence initialization is
available on CodaHx4 and CODA7541 already. Use the profile and level
identification values reported by the firmware to update codec specific
profile and level controls after sequence initialization has succeeded.
