sunxi: Turn on CONFIG_PINCTRL_SUN4I_A10 for A20
CONFIG_PINCTRL_SUN4I_A10 controls both the A10 and the A20 enablong of
the pinctrl driver, this is necessary since upstream commit
5d8d349618a9464714c07414c5888bfd9416638f ("pinctrl: sunxi: add A20
support to A10 driver") which has been included in v4.13 and onwards.
Fixes: ad2b3bf310f7 ("sunxi: Add support for kernel 4.14")
