[PATCH 2/3] Add support for monitoring gpio switches

Select Chromebooks have gpio attached to switches used to cause the
firmware to enter alternative modes of operation and/or control other
device characteristics (such as write protection on flash devices). This
patch adds a driver that exposes a read-only interface to allow these
signals to be read from user space.

This functionality has been generalised to provide support for any device
with device tree support which needs to identify a gpio as being used for a
specific task.

why make it a misc driver?
