1.Modify the macro definition to unify "#define USBPCR_XXXX n" into the "#define USBPCR_XXXX (n << USBPCR_XXXX_LSB)" style, so as to unify the code style in the "jz4770_phy_init()" and simplify the code. 2.Remove unused macro definitions to simplify the code.

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.
