[PATCH -next] pinctrl: artpec6: Make two functions static

[Yue Haibing]

From: YueHaibing <yuehaib...@huawei.com>

Fix sparse warnings:

drivers/pinctrl/pinctrl-artpec6.c:691:5: warning:
 symbol 'artpec6_pmx_enable' was not declared. Should it be static?
drivers/pinctrl/pinctrl-artpec6.c:705:6: warning:
 symbol 'artpec6_pmx_disable' was not declared. Should it be static?
