gpio: qpnp-gpio: Add debugfs support
Add the capability to read and write PMIC gpio parameters through
debugfs on a per chip and gpio basis.
Ex.
pm8941_gpios ->
1 ->
direction
invert
src_select
out_strength
output_type
vin_sel
pull
master_en
2 ->
...
This support is useful for bringup and debugging. It is not
intended to be a replacement for the gpiolib debug support
preexisting in the framework. Use this support for PMIC specific
configurations that cannot be manipulated through the standard
gpiolib interface. Use of this interface is dangerous and can
result in misconfiguration or hardware damage.
