[PATCH] pinctrl: mscc: fix multiple definitions

[Daniel Schwierzeck]

gcc-11 complains about multiple definitions:

/opt/gcc-11.0.20210426-nolibc/mips-linux/bin/mips-linux-ld.bfd: drivers/pinctrl/mscc/pinctrl-ocelot.o:drivers/pinctrl/mscc/mscc-common.h:64: multiple definition of `mscc_pinctrl_ops'; drivers/pinctrl/mscc/mscc-common.o:drivers/pinctrl/mscc/mscc-common.h:64: first defined here
/opt/gcc-11.0.20210426-nolibc/mips-linux/bin/mips-linux-ld.bfd: drivers/pinctrl/mscc/pinctrl-ocelot.o:drivers/pinctrl/mscc/mscc-common.h:66: multiple definition of `mscc_gpio_ops'; drivers/pinctrl/mscc/mscc-common.o:drivers/pinctrl/mscc/mscc-common.h:66: first defined here

mscc_pinctrl_ops and mscc_gpio_ops are instantiated in mscc-common.c and
just referenced by SoC specific pinctrl drivers. Annotate the exports
in mscc-common.h with `extern` to avoid creating new instances
when including mscc-common.h.
