Add optional gpio device tree bindings to the UCD90320. The binding's description is already mentioning the number of GPIOs but without actual gpio controller description.

description: |
|
|
The UCD90320 is a 32-rail PMBus/I2C addressable power-supply sequencer and
|
|
monitor. The 24 integrated ADC channels (AMONx) monitor the power supply
|
|
voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as
|
|
digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for
|
|
margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system
|
|
function.
