audio: policy: add NO_FORCEUSE_ANLG_DOCK for analog dock qualification

FORCE_ANALOG_DOCK always reports a 10 digit value, so this condition will
fail.  Let's qualify on just the FOR_DOCK value (which gets assigned 7
when connected and a 0 when not), when CFLAG: NO_FORCEUSE_ANLG_DOCK is passed.

Note: In jellybean this added qualification is not present.
