> Adding quirk to disable STIG mode since cadence controller has issue for
> read/write using the STIG mode. STIG mode is enabled by default since
> 2023.04 for small read/write(<8bytes).
> 
> Updated STIG mode reading from dev_get_driver_data by assigning to
> platdata struct before read quirks variable.
> 
> The STIG mode is disabled for normal read case and enabled for QSPI Jedec
> ID read/write since it requires STIG read/write.
