ARM: dts: rockchip: remove clock-names property from 'generic-ohci' nodes

A test with the command below gives for example this error:

arch/arm/boot/dts/rv1108-evb.dt.yaml: usb@30160000:
'clock-names' does not match any of the regexes: 'pinctrl-[0-9]+'

'clock-names' is not a valid property name for usb_host nodes with
compatible string 'generic-ohci', so remove them.
