[RESEND 1/1] arch: arm: mach-at91: pm: Move prototypes to mutually included header

From: Lee Jones <hidden>
Date: 2021-03-03 17:11:41 

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)
 | ^~~~~~~~~~~~~~~~~~~~~~~~
