Add binding and driver for the QMP based side-channel communication mechanism
to the AOSS, which is used to control resources not exposed through the RPMh
interface.

Currently implemented is a genpd provider, but pending some improvements in the
thermal framework a cooling device will be added at a later point. Patch 7 is
an "RFC" for how we define and probe these cooling devices.

The remoteproc patches updates the MSS driver to vote for the necessary genpd
corners on SDM845.

Lastly patch 6 makes it possible to have a device on the amba bus where the
apb_pclk is controlled as part of a power-domain.

I'd be fine if you include the binding part now. Looks fine to me.
