This patch adds support for the mode pin GPIO controller and documented
for the same. GPIO Modepin driver set and get the value and status of
the PS_MODE pin, based on device-tree pin configuration.
These 4-bits boot-mode pins are dedicated configurable as input/output.
After the stabilization of the system,these mode pins are sampled.
