The idea is to get rid of the IO abstraction layer inside ASoC and only rely
on regmap for this. This is a process this has been going on ever since the
regmap framework was added to the kernel and we are almost there now. The
best is to implement a regmap bus or a bus-less regmap instance that
implements the IPC for the DSP. If the IPC does not map nicely onto a
register map, we need to come up with something better. It's basically the
same problem that that HDA CODEC by RT has.
