usb: misc: usb3503: support usb3803 and bypass mode
Add support for USB3803 and bypass mode, with this change
is also possible to move the component out of bypass mode.
In bypass mode the downstream port 3 is connected to the
upstream port with low switch resistance R_on.
Controlling mode of operations:
| RESET_N | BYPASS_N | Mode |
--------------------------------
| 0 | 0 | standby |
