Introducing new gpio driver for virtual GPIO devices via virtio.

The driver allows routing gpio control into VM guests, eg. brigding
virtual gpios to specific host gpios, or attaching simulators for
automatic application testing.

Changes v2:
    * fixed uapi header license
    * sorted include's
    * fixed formatting
    * fixed unneeded devm allocation - plain kzalloc/kfree is enough
    * fixed missing devm_kzalloc fail check
    * use devm_kcalloc() for array allocation
    * added virtio-gpio protocol specification

Hi Enrico,

We (Linaro's Project Stratos
https://linaro.atlassian.net/wiki/spaces/STR/overview)
 are interested in this stuff. I was trying to look at the last status
of all this. Few
questions for you:

- Was the spec ever posted to virtio-dev list ? I thought that's the
very first step before
we merge the code.

- Any follow up on this patchset ?

Thanks. I will be happy to help otherwise and have cycles to work on
this if you need my help.
