Current implementation only supports DT, now add ACPI support.

Note that compared to device of 'fsl,qoriq-gpio', LS1028A and
LS1088A's GPIO have no extra programming, so simplify related checking.

Change in v2:
 - Initialize devtype with NULL to fix compile warning.
 - Replace of_device_get_match_data() and acpi_match_device with
device_get_match_data().
 - Replace acpi_match_device() with simpler checking logic per Andy's
suggestion.
