When building a kernel with CONFIG_PM=y but neither suspend nor
hibernate support, the compiler complains about the static functions
twl4030_vibra_suspend() and twl4030_vibra_resume() not being used:

drivers/input/misc/twl4030-vibra.c:176:12: warning: ‘twl4030_vibra_suspend’ defined but not used
drivers/input/misc/twl4030-vibra.c:187:12: warning: ‘twl4030_vibra_resume’ defined but not used

Depending on CONFIG_PM_SLEEP rather than CONFIG_PM fixes the issue.
