When creating MFD platform devices the firmware node is left unset.
This, in particular, prevents GPIO library to use it for different
purposes. Propagate firmware node from the parent device and let
GPIO library do the right thing.
While at it, slightly modify the headers to reflect the usage of APIs.

The DA9062 is a mfd pmic device which supports 5 GPIOs. The GPIOs can
be used as input, output or have a special use-case.
The patch adds the support for the normal input/output use-case.
