Hello Srinivas,
We will add support for vi feedback usecase in sdm845 machine driver
where we have to support 4 channel tx data for a particular backend. We
should probably keep be_hw_params_fixup in respective machine driver for
now to support such requirement.
Thanks,
Rohit

be_hw_fixup for qdsp is common across mutiple qcom machine drivers,
so move it to common file and remove the redundant code.
