Add U1/U2 feature support of xHCI for ZHAOXIN. Since both INTEL and ZHAOXIN need to check the tier where the device is located to determine whether to enabled U1/U2, remove the previous INTEL U1/U2 tier policy and add common policy in xhci_check_tier_policy. If vendor has specific U1/U2 enable policy,quirks can be add to declare.

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.
