commit ea94191e584b146878f0b7fd4b767500d7aae870 upstream.
When initialize cadence qspi controller, it is need to set cqspi to the driver_data field of struct device, because it will be used in function cqspi_remove/suspend/resume(). Otherwise, there will be a crash trace as below when invoking these finctions.
