Stephan Gerhold 1e0b4c07bf gpio: Add driver for Nomadik GPIO ...

Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson
Ux500 SoCs (and some older Nomadik SoCs). It uses registers where
each GPIO is represented as a single bit, plus "set" and "clear"
registers that allow updating the state without having to read the
existing state.

The driver implements support for it for use together with DM_GPIO
and the existing ste-dbx5x0.dtsi device tree.
