Input: st-keyscan - fix 'defined but not used' compiler warnings



Add #ifdef CONFIG_PM_SLEEP around keyscan_supend() and keyscan_resume() to
fix the following compiler warnings occuring if CONFIG_PM_SLEEP is unset:

  + /scratch/kisskb/src/drivers/input/keyboard/st-keyscan.c: warning: 'keyscan_resume' defined but not used [-Wunused-function]:  => 235:12
  + /scratch/kisskb/src/drivers/input/keyboard/st-keyscan.c: warning: 'keyscan_suspend' defined but not used [-Wunused-function]:  => 218:12
