Every pin can be configured now from the device tree. A dt-bindings has been added to describe the different property available.

Changes in v4: - Rebase modification on latest update - Fix typo to read the io-base - Fix direction_output function to set the value
Changes in v3: - Fix the dt-binding copyright header - Remove define for IOBASE and use a property - Fix issues with signed/unsigned variable type - Fix coding style - Add a compatible string for the driver
Changes in v2: - Clean commit message - Rename compatible string 'ich6' to 'x86' - Fix coding style - Create a dt-bindinds documentation - Move x86-gpio defines to a specific header - Reorder the functions to avoid the need for forward declarations - Rename double underscore functions to only one - Create a specific function to configure one pin - Use a define to prevent build/support issues with other x86 CPU that doesn't have a IOBASE.

Applied to u-boot-x86, thanks!
