dt-bindings: usb: ohci: Increase the number of PHYs

commit 0f074c1c95ea496dc91279b6c4b9845a337517fa upstream.

"make dtbs_check":

    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@ee080000: phys: [[17, 0], [31]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ohci.yaml
    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@ee0c0000: phys: [[17, 1], [33], [21, 0]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ohci.yaml

Some USB OHCI controllers (e.g. on the Renesas RZ/G1C SoC) have multiple
PHYs.  Increase the maximum number of PHYs to 3, which is sufficient for
now.
