phy: renesas: rcar-gen3-usb2: Move debug print after register value is updated

Relocate the debug print in rcar_gen3_enable_vbus_ctrl() to appear after
the `val` variable is assigned and updated based on the VBUS state. This
ensures that the debug log reflects the actual register value being
written, improving debugging accuracy.
