[PATCH -next] pinctrl: pinctrl-microchip-sgpio: Mark some symbols with static keyword

[Zou Wei <zou_wei@xxxxxxxxxx>]

Fix the following sparse warnings:

drivers/pinctrl/pinctrl-microchip-sgpio.c:63:31: warning: symbol 'properties_luton' was not declared. Should it be static?
drivers/pinctrl/pinctrl-microchip-sgpio.c:68:31: warning: symbol 'properties_ocelot' was not declared. Should it be static?
drivers/pinctrl/pinctrl-microchip-sgpio.c:73:31: warning: symbol 'properties_sparx5' was not declared. Should it be static?
