Subject: [PATCH 5.15 091/135] dt-bindings: usb: ehci: Increase the number of PHYs

From: Geert Uytterhoeven <geert+renesas@...der.be>

commit 9faa1c8f92f33daad9db96944139de225cefa199 upstream.

"make dtbs_check":

    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@...80100: phys: [[17, 0], [31]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ehci.yaml
    arch/arm/boot/dts/r8a77470-iwg23s-sbc.dtb: usb@...c0100: phys: [[17, 1], [33], [21, 0]] is too long
	    From schema: Documentation/devicetree/bindings/usb/generic-ehci.yaml

Some USB EHCI 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.
