Subject: spi: cadence: set cqspi to the driver_data field of struct device
Git-commit: ea94191e584b146878f0b7fd4b767500d7aae870
Patch-mainline: v5.12-rc4
References: git-fixes

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.
