To support XUSB host controller ELPG, this commit moves VBUS control .phy_power_on()/.phy_power_off() to .phy_init()/.phy_exit(). When XUSB host controller enters ELPG, host driver invokes .phy_power_off(), VBUS should remain ON so that USB devices will not disconnect. VBUS can be turned OFF when host driver invokes .phy_exit() which indicates disabling a USB port.

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.
