phy: renesas: rcar-gen3-usb2: Simplify ID/VBUS detection logic
Read USB2_ADPCTRL once in rcar_gen3_check_id() instead of issuing
multiple MMIO reads, and derive both IDDIG and VBUSVALID from the same
value.
Drop the redundant !! operator, as assigning a masked u32 value to a
bool already performs the required normalization. Simplify the logic by
comparing the ID and VBUS status directly, which is equivalent to the
previous conditional but easier to follow.
