[media] STV0299 incorrect standby setting issues register 02 (MCR)

Browse Source 
Issues with Register 02 causing spurious channel locking from standby.
Should have always bits 4 & 5 written to 1.
Lower nibble not used in any current driver. Usage if necessary can be
applied through initab to mcr_reg. stv0299 not out of standby before
writing inittab.
