In certain PMICs, when WLED is configured for AMOLED panels, AVDD
default voltage configured for SWIRE mode has to be reconfigured
every time WLED module is disabled and enabled. Otherwise, AVDD
voltage can stay at the previous voltage level configured through
SWIRE pulses. Add support for it.

Sometimes, OVP fault interrupt fires as soon as WLED module is
enabled. This does not really represent a harmful event. Hence
add support to enable OVP fault interrupt 10 mS after enabling
WLED module so that the soft start is completed. Keep the OVP
fault interrupt disabled when the module is disabled.
While at it, print the fault status from both OVP and short
circuit interrupt handlers which might be useful.

Currently multiple regulator devices can be specified for LED
switch device though a switch device may just require one supply.
Also, before the switch device is enabled, voltage request is
sent to set the maximum voltage. This is not needed with the
regulators like BoB being used as supply for the switch device.
Just enabling the regulator is enough during switch operation.
Modify the way the regulator is obtained and controlled for
switch operation.
Since BoB regulator is configured by the bootloader properly
for flash operation, remove them from the supply list of LED
switch devices on pmicobalt and pm2falcon.
While at it, fix the way device tree properties are read from
flash/torch, switch devices.
