soundwire: qcom: remove unused rd_fifo_depth

Browse Source 
remove read fifo depth field parsing logic, as rd_fifo_depth is never
used in the driver. Cleaning this up would benefit when adding new
variant support which includes adding variant fields for rd_fifo_depth.

ex: Glymur has this rd_fifo_depth register fields changed from v2.x
