ASoC: qdsp6: q6routing: Conditionally reset FrontEnd Mixer
Streams are resused across multiple BackEnd mixers, do not reset the
stream mixers if they are not already set for that particular FrontEnd.
Ex:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
woudld set the MultiMedia1 steam for SLIMBUS_0_RX, however doing below
amixer command will reset previously setup MultiMedia1 stream.
amixer cset iface=MIXER,name='SLIMBUS_2_RX Audio Mixer MultiMedia1' 0
So reset the FrontEnd Mixers conditionally.
