Mika Westerberg a7d2bf25a4 HID: i2c-hid: Do not fail probing if gpiolib is not enabled 
Using GPIOs and gpiolib is optional. If the kernel is compiled without GPIO
support the driver should not fail if it finds the interrupt using normal
methods.

However, commit a485923efb ("HID: i2c-hid: Add support for ACPI GPIO
interrupts") did not take into account that acpi_dev_add_driver_gpios()
returns -ENXIO when !CONFIG_GPIOLIB.

Fix this by checking the return value against -ENXIO and 0 and only in that
case fail the probe.
