The NPLL is the only safe way to generate 500 MHz for the GPU. The
downstream Chrome OS 3.14 kernel ('official' kernel for veyron
devices) re-purposes NPLL to HDMI and hence disables the OPP for
the GPU (see https://crrev.com/c/1574579). Disable it here as well
to keep in sync and avoid problems in case someone decides to
re-purpose NPLL.

[moved from veyron to general rk3288, as tying up the NPLL for a
not-that-helpful opp (not really fast but will still generate
quite a bit of heat) doesn't make so much sense when it will
keep us from supporting other display modes in the future]

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.
