Add the pinctrl-k210.c pinctrl driver for the Canaan Kendryte K210 field programmable IO array (FPIOA) to allow configuring the SoC pin functions. The K210 has 48 programmable pins which can take any of 256 possible functions. This patch is inspired from the k210 pinctrl driver for the u-boot project and contains many direct contributions from Sean Anderson. The MAINTAINERS file is updated, adding the entry "CANAAN/KENDRYTE K210 SOC FPIOA DRIVER" with myself listed as maintainer for this driver.
