As for other drivers with similar pattern, please make use of
the spi_device_id->driver_data to provide the chip_info pointer
if the of_device_get_match_data() returns NULL.

A side effect of adding this spi_device_id table is that
it enables board file and other non firmware based forms
of device instantiation.
