The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. This example was doing it correctly
but I am proposing dropping this so as to reduce chance of cut and paste
where it is done wrong.  Also drop now unneeded linux/acpi.h include and
added linux/mod_devicetable.h for struct acpi_device_id definition.
