pinctrl: zynq: Fix typos in smc0_nand_grp and smc0_nor_grp

Group names should be smc0_nand_grp and smc0_nor_grp, otherwise you'll
get errors like this if you try to pinmux them via the devicetree:
zynq-pinctrl 700.pinctrl: invalid group "smc0_nand_grp" for function "smc0_nand"

Probably a typo while creating these tables.
