'simple-mfd' also means the child nodes have zero dependence on the
parent node and its resources.

That is correct. The regulators have zero dependencies on the audio codec
resources (clocks/resets/etc.). The _only_ relationship is the overlapping
address of the MMIO register.

LDO registers are at the end of analogue codec MMIO space, right? We can 
easily split that to separate device, like it's been done for A20 timer & 
watchdog.

No, there are some audio-related registers after the LDO register ("POWER_REG" in the D1 and V853 manuals).
So it is not possible to cleanly split the MMIO region.
