Add cpu aliases to U-Boot specific dtsi for hifive-unleashed. Without aliases we see that the CPU device sequence numbers are set randomly and the cpu list/detail command will show it as follows: => cpu list 1: cpu@0 rv64imac 0: cpu@1 rv64imafdc 2: cpu@2 rv64imafdc 3: cpu@3 rv64imafdc 4: cpu@4 rv64imafdc
Seems like CPU probing with dm-model also relies on aliases as observed in case spi. The fu540-c000-u-boot.dtsi has cpu0/1/2/3/4 nodes and so adding corresponding aliases we can ensure that cpu devices are assigned proper sequence as follows:
=> cpu list 0: cpu@0 rv64imac 1: cpu@1 rv64imafdc 2: cpu@2 rv64imafdc 3: cpu@3 rv64imafdc 4: cpu@4 rv64imafdc
