It can be useful to control the different power states of various
parts of hardware for device testing. Add a debugfs node for qmp so
messages can be sent to aoss for debugging and testing purposes.
Is it ever useful after device testing? I'd prefer we not apply this
patch as it looks like testing code that won't ever be used after
developing this driver.
This is not only for testing. Some user space clients can also use this
to send messages to aoss.
One such example is setting higher ddr frequency during boot and
reducing it post boot from user space.
