Fix the following warnings:
arch/sparc/power/hibernate.c:22:5: warning: no previous prototype for ‘pfn_is_nosave’
arch/sparc/power/hibernate.c:30:6: warning: no previous prototype for ‘save_processor_state’
arch/sparc/power/hibernate.c:35:6: warning: no previous prototype for ‘restore_processor_state’

The prototypes are available from linux/suspend.h so include that.
