Since the core regulator code is treating GPIO descriptors as
nonexclusive, i.e. it assumes that the enable GPIO line may be
shared with several regulators, let's add the flag introduced
for fixing this problem on fixed regulators to all drivers
fetching GPIO descriptors to avoid possible regressions.

Instead of passing a global GPIO number, pass a descriptor looked
up with the standard devm_gpiod_get_index_optional() call.

Vpos and Vneg LDOs can be enabled or disabled by external GPIOs.
Use general DT property 'enable-gpios' for this usage.
Two enable pins are differentiable by selecting the index number.

LM363X regulator driver supports LM3631 and LM3632.
LM3631 has 5 regulators. LM3632 provides 3 regulators.
One boost output and LDOs are used for the display module.
Boost voltage is configurable but always on.
Supported operations for LDOs are enabled/disabled and voltage change.
Two LDOs of LM3632 can be controlled by external pins.
Those are configured through the DT properties.
