regulator: dt-bindings: richtek,rt4801: use existing ena_gpiod feature

Browse Source 
The binding and driver duplicated regulator core feature of controlling
regulators with GPIOs (of_parse_cb + ena_gpiod) and created its own
enable-gpios property with multiple GPIOs.

This is a less preferred way, because enable-gpios should enable only one
element, not multiple. It also duplicates existing solution.

Deprecate the original 'enable-gpios' and add per-regulator property.
