Without this, dev_get_plat() may return invalid or uninitialized platform data when multiple XSPI controllers are present, leading to incorrect IOBASE/SDMABASE/AUXBASE values and causing SPI flash probe failures. Setting .plat_auto ensures each controller instance receives a properly sized cdns_xspi_plat structure, allowing SF probe to work correctly. Tested on an Altera Simics platform with multiple XSPI controllers.
