Replace the custom arizona_of_get_type() function with the generic device_get_match_data() helper. Besides being a nice cleanup this also makes it easier to add support for binding to ACPI enumerated devices. While at it also fix a possible NULL pointer deref of the id argument to the probe functions (this could happen on e.g. manual driver binding through sysfs).
