ARC: [dts] fix the errors detected by dtbs_check

xxx/arc/boot/dts/axs101.dt.yaml: dw-apb-ictl@e0012000: $nodename:0: \
'dw-apb-ictl@e0012000' does not match '^interrupt-controller(@[0-9a-f,]+)*$'
 From schema: xxx/interrupt-controller/snps,dw-apb-ictl.yaml

The node name of the interrupt controller must start with
"interrupt-controller" instead of "dw-apb-ictl".
