ASoC: SOF: debug: Add generic API and ops for DSP regions

Browse Source 
Add new debugfs_add_region_item along with a generic wrapper
snd_sof_debugfs_add_region_item() to abstract away the DSP regions related
debugfs support.

At the same commit add iomem based generic implementation for the new ops
