Viresh Kumar 3a29355a22 gpio: Add virtio-gpio driver
This patch adds a new driver for Virtio based GPIO devices.

This allows a guest VM running Linux to access GPIO lines provided by
the host. It supports all basic operations, except interrupts for the
GPIO lines.

Based on the initial work posted by:
"Enrico Weigelt, metux IT consult" <lkml@metux.net>.
