arm64: versal: Add qspi flash mini u-boot configuration
Add configuration file for mini u-boot configuration which runs on a
smaller footprint from on chip memory(OCM). This configuration has
required CONFIG's enabled to support qspi flash and uses DCC terminal
for console output. Add required dts files for qspi mini configuration.
