Enable sound and modem for the Longcheer L8910 (BQ Aquaris X5).
The setup is similar to most MSM8916 devices, i.e.:

 - QDSP6 audio
 - Earpiece/headphones/microphones via digital/analog codec in
   MSM8916/PM8916
 - Audio jack detection via analog codec in PM8916
 - WWAN Internet via BAM-DMUX

except:

 - Awinic AW8738 connected to HPH_R (headphones) output of the analog
   codec. Note that unlike for wingtech-wt88047 there is no analog
   switch that would allow disabling output via the headphone jack
   when the speaker is enabled.
