I just checked it on latest linux-next and all good on my side. Would it be 
possible that you don't have commit 2da2740fb9c8 ("soc: renesas: rz-sysc: Add 
syscon/regmap support") in your tree?

This is how my tree looks like:

1db69bbb9c49 (HEAD) arm64: dts: renesas: rzg3s-smarc: Enable USB support
ee93ed9f0097 arm64: dts: renesas: r9a08g045: Add USB support
285447f934f3 reset: rzg2l-usbphy-ctrl: Add support for RZ/G3S SoC
8c758908876c reset: rzg2l-usbphy-ctrl: Add support for USB PWRRDY
8e41c54ab567 dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/G3S support
02db7a65b4b3 phy: renesas: rcar-gen3-usb2: Fix an error handling path in 
rcar_gen3_phy_usb2_probe()
217453b58bdf dt-bindings: phy: renesas,usb2-phy: Mark resets as required for RZ/G3S
0f4c93f7eb86 (tag: next-20250822, linux-next/master) Add linux-next specific 
files for 20250822

and few checks on my board:
