Ville Syrjälä 319b0869f5 drm/i915: Remove PLL asserts from .load_luts()
.load_luts() potentially runs from the vblank worker, and is
under a deadline to complete within the vblank. Thus we can't
do expesive stuff like talk to the Punit, etc.

To that end get rid of the assert_dsi_pll_enabled() call for
vlv/chv. We'll just have to trust that the PLL is already enabled
here.

And I don't think the normal assert_pll_enabled() really buys us
anything useful on gmch platforms either, so nuke that one too.
We don't have corresponding asserts in the ilk+ codepaths anyway
despite the hardware (IIRC) still requiring the clock to be
enabled when we access the LUT.

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.
