ASoC: SOF: Split up utils.c into sof-utils and iomem-utils
The utils.c contains wrappers and implementation for accessing iomem mapped
regions and a single unrelated function to create a compressed page table
from snd_dma_buffer for firmware use.
The latter is used by the PCM and the dma trace code and it needs to be
moved to a generic source/header for the client conversion to be possible.
