pinctrl: pinctrl-loongson2: fix Kconfig dependency

If CONFIG_PINCTRL_LOONGSON2=y and CONFIG_OF is not set,
gcc complained about undefined reference:

drivers/pinctrl/pinctrl-loongson2.o: In function `pinconf_generic_dt_node_to_map_all':
pinctrl-loongson2.c:(.text+0x1c4): undefined reference to
`pinconf_generic_dt_node_to_map'

To fix this error, add depends on OF to
config PINCTRL_LOONGSON2.
