Subject: [PATCH] arm64: dts: HiSilicon: hi3660: address a PCI warning

When the driver is registered, it produces a warning when
registering the PCI bridge:

	[    5.363450] pci_bus 0000:00: root bus resource [bus 00-01]
	[    5.396998] pci_bus 0000:01: busn_res: can not insert [bus 01-ff] under [bus 00-01] (conflicts with (null) [bus 00-01])
	[    5.284831] pci 0000:00:00.0: PCI bridge to [bus 01-ff]

The reason is that the bus-range is wrong. Address it.
