ASoC: msm: Fix FM glitch issue.
For FM glitch issue, currently unity gain is being applied
as driver is not sending afe loopback gain cmd to LPASS before
afe loopback start cmd. afe loopback gain fails when
sent before sending loopback start cmd, as there is no APR
registration implemented. Adding APR registration to the cmd
to address the issue.
