Add support for the ACONNECT bus which is part of the audio sub-system
on Tegra210.

I did look to see if we could use the simple-pm-bus infrastructure for
this, however, in the end I found that it did was not a good fit because
of the way clocks for the bus are handled. The simple-pm-bus is tightly
coupled to the genpd subsystem and is reliant on the power-domain
associated with the bus to have the flag GENPD_FLAG_PM_CLK set and uses
the genpd function pointer, attach_dev(), as a hook to populate the
clocks. For Tegra this does not work because the power-domains are
instantiated from device-tree rather than platform code. In this case
for Tegra it is simpler to keep the clock management of devices within
the power-domain separated from the power-domain itself.
