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.
Call trace:
cqspi_suspend+0x14/0x44
dpm_run_callback+0x50/0x1c0
__device_suspend+0x114/0x514

el0_svc+0x20/0x30
el0_sync_handler+0x1a4/0x1b0
