ASoC: SOF: ops: fallback to mmio in helpers
Returning an error when a read/write is not implemented makes no
sense, especially on read where no return value makes sense.
Change the logic to directly fallback to mmio. If a platform truly
wants other read/writes that are not plain vanilla mmio, it needs to
implement its own routines.
