gpio: moxart: Switch to using the FTGPIO010 driver
This just deletes the Moxa ART driver and replaces it with the more versatile Faraday FTGPIO010 driver. Make this default on for ARCH_GEMINI and ARCH_MOXART so we do not get Kconfig glitches. Tested-by: Jonas Jensen <jonas.jensen@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
