The USB PHY IP in the Allwinner H616 SoC requires a quirk that involves some resources from port 2's PHY and HCI IP. In particular the PMU clock for port 2 must be surely ungated before accessing the REG_HCI_PHY_CTL register of port 2. To allow each USB port to be controlled independently of port 2, we need a handle to that particular PMU clock in the *PHY* node, as the HCI and PHY part might be handled by separate drivers. Add that clock to the requirements of the H616 PHY binding, so that a PHY driver can apply the quirk in isolation, without requiring help from port 2's HCI driver.

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.
