This patch adds the necessary files to use a modern pinctrl driver
with an exynos5250 SoC. The changes are well tested and are working.
GPIO isn't implemented right now, as the older s5p_gpio driver needs
to be disabled for the newer driver to work.
All changes were tested with soon-to-be upstreamed DTs for the
Linux kernel. The tested device is a Google Nexus 10 (samsung-manta).
U-Boot was ported to that device and will be upstreamed into U-Boot
soon.
I don't have much experience with the mailing list workflow, u-boot
or driver development in general. I apologize for any mistakes I might
do.
