ASoC: update snd_pcm_ops copy interface in platform drivers

Browse Source 
snd_pcm_ops copy interface used by msm platform drivers is replaced
with copy_user in msm-4.14. Unit of two input variables is changed
from frame count to byte.
Update all the related msm platform drivers to adapt to this change.
