regulator: lm363x: Use generic property for hardware enable pins

Browse Source 
With index usages, device specific properties can be replaced with generic
one. Vpos is index 0 and Vneg is index 1.
DT examples are added as well.

Optional properties:
LM3632 has external enable pins for two LDOs.
- ti,lcm-en1-gpio: A GPIO specifier for Vpos control pin.
- ti,lcm-en2-gpio: A GPIO specifier for Vneg control pin.
- enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins.
The first entry is Vpos, the second is Vneg enable pin.
