cpufreq: ti-cpufreq: omap36xx use "cpu0","vbb" if run in multi_regulator mode
In preparation for using the multi_regulator capability of
this driver for handling the ABB LDO for OPP1G of the omap36xx
we have to take care that the (legacy) vdd-supply name is
cpu0-supply = <&vcc>;
To do this we add another field to the SoC description table which
optionally can specify a list of regulator names.
For omap36xx we define "cpu0-supply" and "vbb-supply".
The default remains "vdd-supply" and "vbb-supply".
