libhardware_legacy: Support LPA Playback

Add support to enable Playback in LPA mode

When Alarm is playing on headset+spkr, if LPA
playback is selected STARTEGY_MEDIA gets selected
and switches device from Combo device to Headset.
- Fix the issue by selecting Combo device only
even incase of LPA when stream ALARM/NOTIFICATION
is active.
