Add support for the adp5589 I/O expander. From a PWM point of view it is
pretty similar to adp5585. Main difference is the address
of registers meaningful for configuring the PWM.

Make sure to enable the oscillator in the top device. This will allow to
not control this in the child PWM device as that would not work with
future support for keyboard matrix where the oscillator needs to be
always enabled (and so cannot be disabled by disabling PWM).

It turns out that OSC_EN bit in GERNERAL_CFG register has to be set to 1
when PWM state is enabled, otherwise PWM signal won't be generated.

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the PWM function using the platform device
registered by the core MFD driver.
The driver is derived from an initial implementation from NXP, available
in commit 113113742208 ("MLK-25922-1 pwm: adp5585: add adp5585 PWM
support") in their BSP kernel tree. It has been extensively rewritten.
