From: Meng Li <Meng.Li@windriver.com>
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 el0_sync+0x174/0x180
