phy: renesas: rcar-gen3-usb2: Check a property to use otg pins
Since All R-Car Gen3 SoCs have dedicated otg pins actually but some boards don't use the otg pins (e.g. R-Car D3 Draak and R-Car E3 Ebisu), the driver should not choose SoC model base by using rcar_gen3_phy_usb2_match_table's data. So, this patch checks a "renesas,no-otg-pins" property to set the "uses_otg_pins". Note that since r8a77995-draak.dts and r8a77990-ebisu.dts don't have 'dr_mode = "otg";' for now, if we apply this patch, no behavior changes (the value of "uses_otg_pins" is false).
