introduce MEN 16Z127 GPIO controller driver

This patch adds the MEN 16Z127 GPIO Controller driver, which is 32bit wide and located within a MCB FPGA.

changes in v2:
- ported driver to use the generic MMIO library
- added open drain support
- added debounce support

The 16Z127 is a 32bit GPIO controller on a MCB FPGA. Every single line can be configured as input and output.

Push pull and open drain are supported as well as setting a debounce value for the input lines.
