This patch adds the GPIO port 3 driver with the following functions:
set/get pin values, direction_in/out, set_debounce.
The values are also available to the userspace (if requiered)
in the path /sys/class/gpio by using the export/unexport functions.
Please look at the REVISIT comment, this is the main reason of the RFC,
suggestions will be highly appreciated.

This is calling for a MFD driver for these chips. This was proposed in
the past, BTW, but never followed up:

Putting everything in the current driver is not going to be accepted.
It certainly looks pleasant because it's a more simple approach, but
the result would be a complex and unmaintainable driver.
