Ville Syrjälä 6501e6bb14 drm/i915: Clean up gen2 DPLL readout
The current gen2 DPLL readout code:
* assumes i845/i865 have LVDS which is not true
* assumes only pipe B can drive LVDS (true, but makes
  the code appear a bit magical)
* hard to parse in general

Clean it up by checking for i85x (the only gen2 platform
with LVDS) and reusing intel_lvds_port_enabled().

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.
