ARM: at91: pm: Move prototypes to mutually included header
Both the caller and the supplier's source file should have access to
the include file containing the prototypes.
Fixes the following W=1 kernel build warning(s):
drivers/pinctrl/pinctrl-at91.c:1637:6: warning: no previous prototype for ‘at91_pinctrl_gpio_suspend’ [-Wmissing-prototypes]
1637 | void at91_pinctrl_gpio_suspend(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/pinctrl/pinctrl-at91.c:1661:6: warning: no previous prototype for ‘at91_pinctrl_gpio_resume’ [-Wmissing-prototypes]
1661 | void at91_pinctrl_gpio_resume(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~
