ACPI / button: fix button driver compile error when CONFIG_PM_SLEEP is undefined

Browse source 
The ACPI button driver defines acpi_button_resume() when
CONFIG_PM_SLEEP is defined. This results in the following
compile error when CONFIG_PM_SLEEP is undefined:

drivers/acpi/button.c:85:8: error: ‘acpi_button_resume’ undeclared here (not in a function)
