This patch adds a GPIO controller support targeted for NXP LS1046A
SoC. The driver implements the following features:
* setting direction of each pin (IN or OUT)
* setting the mode of output pins (PUSHPULL or OPENDRAIN)
* setting the state of each output pin (1 or 0)
* reading the state of each input pin (1 or 0)
