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.
