Add a Git tree on @kernel.org for maintaining the Samsung pinctrl
drivers. The tree will be maintained in a shared model between current
Samsung pinctrl maintainers. Pull requests will be going to Linus
Walleij.
Also add the patchwork for linux-samsung-soc mailing list which will be
used for handling the patches.
