Button GPEs have been enabled in the acpi_wake_device_init() during
boot and Button driver enables these GPEs second time. This causes
disabling these gpes via sysfs interface requires twice "echo disable
> /sys/firmware/acpi/interrupts/gpeXXX". This patch is to remove
related code in the Button driver.
