Merge tag 'hisi-arm64-dt-for-4.17' of git://github.com/hisilicon/linux-hisi into next/dt

Pull "ARM64: DT: Hisilicon SoC DT updates for 4.17" from Wei Xu:

- Add XGE CPLD control support for hip07 SoC
- Disable the SMMU on hip06 and hip07 SoCs becuase of
  the hardware limitation
- Enable HS200 mode for the MMC controller on hi6220 hikey board
- Remove "cooling-{min|max}-level" this kind unused properties
  for hi6220 SoC
- Add watchdog node for hi6220 SoC
- Remove "CPU_NAP" idle state on hikey960 board since it is
  not stable and useless with the updated firmware

* tag 'hisi-arm64-dt-for-4.17' of git://github.com/hisilicon/linux-hisi:
