pinctrl: add a Gemini SoC pin controller
This adds a pin control (only multiplexing) driver for the Gemini SoC so we can sort out this complex platform in an orderly manner. This driver will detect the chip/package version as SL3512 or SL3516 (also known as CS3512 and CS3516 etc) and register the apropriate pin set. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
