Subject: [PATCH] ARM: at91: pm: change at91_pm_set_standby() to static

Since at91_pm_set_standby() will not be used out of the pm.c file,
change its attribute from extern to static, remove its declaration as well.

void at91_pm_set_standby(void (*at91_standby)(void))
-->
static void at91_pm_set_standby(void (*at91_standby)(void))
