phy: rockchip-inno-usb2: Implement clock operations for usb2phy clock

This clock doesn't seem needed but appears in a phandle list used by
ehci-generic.c to bulk enable it. The phandle list comes from linux,
where it is needed for suspend/resume to work [1].

My tests give the same results with or without this patch, but Marek
Vasut found it weird to declare an empty clk_ops [2].

So I adapted the code from linux 6.1-rc8 so that it hopefully works
if it ever has some user. For now, without real use, it seems to
at least not give any errors when called.
