pinctrl: get rid of all platform data for coh901
This deletes the dependency on any platform data for the COH901 pin controller. There is only one user in the kernel, and if we at some point want to support more variants, they shall provide their variant info through the device tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
