Enric Balletbo i Serra ebfee0309d usb: dwc3: rockchip: Fix PHY documentation links.
Commit 34962fb807 ("docs: Fix more broken references") replaced the
broken reference to rockchip,dwc3-usb-phy.txt binding for the Qualcomm
DWC3 binding (qcom-dwc3-usb-phy.txt). That's wrong, so replace that
reference for the correct ones.

Rockchip SuperSpeed DWC3 USB SoC controller
Required properties:
- compatible: should contain "rockchip,rk3399-dwc3" for rk3399 SoC
- clocks: A list of phandle + clock-specifier pairs for the
clocks listed in clock-names
- clock-names: Should contain the following:
"ref_clk" Controller reference clk, have to be 24 MHz
"suspend_clk" Controller suspend clk, have to be 24 MHz or 32 KHz
"bus_clk" Master/Core clock, have to be >= 62.5 MHz for SS
operation and >= 30MHz for HS operation
"grf_clk" Controller grf clk
Required child node:
A child node must exist to represent the core DWC3 IP block. The name of
the node is not important. The content of the node is defined in dwc3.txt.
Phy documentation is provided in the following places:
Documentation/devicetree/bindings/phy/phy-rockchip-inno-usb2.txt - USB2.0 PHY
Documentation/devicetree/bindings/phy/phy-rockchip-typec.txt - Type-C PHY
