Add U-Boot specific dts file for hifive-unleashed-a00, this would help to add u-boot specific properties and other node changes without touching the base dts(i) files which are easy to sync from Linux.

Added spi2 alias for qspi2 as an initial u-boot specific property change.

spi probing in current dm model is very much rely on aliases numbering. Even though the qspi2 can't come under any associated spi nor flash it would require to specify the same to make proper binding happen for other spi slaves.
