[PATCH 2/2] fpga: ts73xx-fpga: add OF match table for device tree probing

The ts73xx-fpga driver currently only matches by platform device name,
which prevents it from being probed when the device is described in a
device tree. Add an of_device_id table so the driver can match against
the "technologic,ts73xx-fpga" compatible string.
