acer-wmi: Hide acer_{suspend,resume} for !CONFIG_PM_SLEEP 

Encapsulate acer_suspend() and acer_resume with #ifdef CONFIG_PM_SLEEP
to get rid of the following warnings:

  ../acer-wmi.c:2046:12: warning: ‘acer_suspend’ defined but not used [-Wunused-function]
  ../acer-wmi.c:2068:12: warning: ‘acer_resume’ defined but not used [-Wunused-function]
