Chris Wilson 13c5a577b3 drm/i915/gt: Select the deepest available parking mode for rc6
On Ivybridge, we can go lower than rc6 to rc6p. And this is required for
Ivybridge to hit the same minimum power consumption as rc6 on other
platforms, so make it so.

v2: Update selftest to include all rc6 residency counters

Note that Andi did mention that we should be converting the magic
numbers into opaque magic macros, so if they ever get reused (unlikely
given only Ivybridge used the extra modes) we'll need to pay back the
technical debt.

README

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.
