[PATCH 3/3] ehci-platform: add the max clock number to 4

[Icenowy Zheng]

			clocks = <&ccu CLK_A64_BUS_OHCI1>,
				 <&ccu CLK_A64_BUS_EHCI1>,
				 <&ccu CLK_A64_USB_OHCI0>,
				 <&ccu CLK_A64_USB_OHCI1>;

On A64, EHCI requires the matched OHCI to work.
And OHCI1 clock requires OHCI0 clock to work.

(But from the SoC's user manual we cannot get any infomation
about the relationship between OHCI1 clock and OHCI0 clock,
and in the manual OHCI0 clock is called OTG-OHCI)
