dt-bindings: mfd: Add Analog Devices ADP5585 



The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
These bindings model the device as an MFD, and support the GPIO expander
and PWM functions.

These bindings support the GPIO and PWM functions.

Drop the existing adi,adp5585 and adi,adp5585-02 compatible strings from
trivial-devices.yaml. They have been added there by mistake as the
driver that was submitted at the same time used different compatible
strings. We can take them over safely.
