Subject: [PATCH] arm64: dts: rockchip: rk3368 swap clust0 and clust1

Before this patch, clust1 has little core0~3, clust0 has big core0~3
cpu_l | cpu0 |
cpu_l | cpu1 | clust1
cpu_l | cpu2 |
cpu_l | cpu3 |
----------------------
cpu_b | cpu4 |
cpu_b | cpu5 | clust0
cpu_b | cpu6 |
cpu_b | cpu7 |

With this patch, clust0 will have little core0~3, clust1 will have big core0~3
cpu_l | cpu0 |
cpu_l | cpu1 | clust0
cpu_l | cpu2 |
cpu_l | cpu3 |
----------------------
cpu_b | cpu4 |
cpu_b | cpu5 | clust1
cpu_b | cpu6 |
cpu_b | cpu7 |

It makes no other change, just keep same with other SoCs definations.
