ARM: ep93xx: move pinctrl interfaces into include/linux/soc
ep93xx does not have a proper pinctrl driver, but does things ad-hoc through mach/platform.h, which is also used for setting up the boards. To avoid using mach/*.h headers completely, let's move the interfaces into include/linux/soc/. This is far from great, but gets the job done here, without the need for a proper pinctrl driver.
