spi: cadence-quadspi: Assume device could match via platform

Driver has only of_device_id table, however it also has MODULE_ALIAS()
for platform name, thus assume there is a configuration where this can
be loaded outside of OF system.  In such case of_device_get_match_data()
will return NULL, which is already checked in one place of probe()
function but not in the other, leading to Smatch warning:

  drivers/spi/spi-cadence-quadspi.c:1942 cqspi_probe() error: we previously assumed 'ddata' could be null (see line 1885)

Driver should be consistent, so assume device can be matched via
platform bus and of_device_get_match_data() can indeed return NULL.
This is also possible with malformed DTS on OF-platform: no unit address
and device node name matching driver name.
