Current USB3503 driver ignores GPIO polarity and always operates as if the GPIO lines were flagged as ACTIVE_HIGH. Fix the polarity for the existing USB3503 chip applications to match the chip specification and common convention for naming the pins. The only pin, which has to be ACTIVE_LOW is the reset pin. The remaining are ACTIVE_HIGH. This change allows later to fix the USB3503 driver to properly use generic GPIO bindings and read polarity from DT.
