[PATCH] pinctrl: nomadik: fix warnings from unexported functions

[Ben Dooks <ben.dooks@xxxxxxxxxxxxxxx>]

There are five functions in the driver that are defined but
only used locally. Make these static to avoid the following
warnings:

drivers/pinctrl/nomadik/pinctrl-nomadik.c:1036:6: warning: symbol 'nmk_gpio_clocks_enable' was not declared. Should it be static?
drivers/pinctrl/nomadik/pinctrl-nomadik.c:1050:6: warning: symbol 'nmk_gpio_clocks_disable' was not declared. Should it be static?
drivers/pinctrl/nomadik/pinctrl-nomadik.c:1073:6: warning: symbol 'nmk_gpio_wakeups_suspend' was not declared. Should it be static?
drivers/pinctrl/nomadik/pinctrl-nomadik.c:1094:6: warning: symbol 'nmk_gpio_wakeups_resume' was not declared. Should it be static?
drivers/pinctrl/nomadik/pinctrl-nomadik.c:1120:6: warning: symbol 'nmk_gpio_read_pull' was not declared. Should it be static?

Note, this now produces warnings that these functions
are defined but not used.
