Cross checked with HW team again. Along with refgen, there is a on-chip
LDO which supplies fixed voltage to the PHYs. It is enabled upon system
power on and no SW intervention is required.
regulator-fixed doesn't take the resource 'reg'. May be should I create
another regulator driver which accepts 'reg', something similar to the
qcom-refgen-regulator? Please advise.
