Add properties for regmap to the regulator-fixed device tree binding:
* Reference the regmap phandle
* Specify the enable offset and enable mask
* Reuse enable-active-high for regmap
This is required for Broadcom BCM63xx SoCs that enable power to
individual peripherals by clearing a bit in the miscIddqCtrl register.
