Emanuele Ghidoli b91e610711 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 |
|    1    |    0     | bypass  |
|    1    |    1     | hub     |

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
