WIP: audio: pipeline: disable pipeline position registers

Disable the code to set up pipeline position registers
using the sof_get() singleton instance. This design is not
feasible when pipelnes are running in user-space and an alternative
implementation is needed.

This is not required in initial LL user testing as position
reporting via pipeline register is not used in all configurations.
