The current pinconf packed format allows only 16-bit argument limiting
the maximum value 65535. For most types this is enough. However,
debounce time can be in range of hundreths of milliseconds in case of
mechanical switches so we cannot represent the worst case using the
current format.
In order to support larger values change the packed format so that the
lower 8 bits are used as type which leaves 24 bits for the argument.
This allows representing values up to 16777215 and debounce times up to
16 seconds.
We also convert the existing users to use 32-bit integer when extracting
argument from the packed configuration value.

The strucuture 'max77620_cfg_param' is defined but never used by the
max77620 driver. Remove this structure definition.

MAXIM Semiconductor's PMIC, MAX77620/MAX20024 has 8 GPIO pins
which also act as the special function in alternate mode. Also
there is configuration like push-pull, open drain, FPS timing
etc for these pins.
Add pin control driver to configure these parameters through
pin control APIs.
