arm/dt: msm8610: Add the on-demand supplies for audio codec
There are several supplies needed for audio codec to function. But some
of the supplies can be disabled if not needed to reduce the system power
assumption. Add the on-demand supplies so the audio codec driver can
disable or enable these supplies.
