Enable flash reset functionality for Versal NET platform. In cadence_qspi.c there is weak function defined for reset, hence remove the check for config, so that it will work for Versal and Versal NET platforms. Add register defines in Versal NET hardware.h for mini U-Boot flash reset. Add read_delay initialization for Versal NET also.
