José Roberto de Souza 995e9bcb42 drm/i915/display/dg1: Correctly map DPLLs during state readout
_DG1_DPCLKA0_CFGCR0 maps between DPLL 0 and 1 with one bit for phy A
and B while _DG1_DPCLKA1_CFGCR0 maps between DPLL 2 and 3 with one
bit for phy C and D.

Reusing _cnl_ddi_get_pll() don't take that into cosideration returing
DPLL 0 and 1 for phy C and D.

That is a regression introduced in the refactor done in
commit 351221ffc5 ("drm/i915: Move DDI clock readout to
encoder->get_config()").
While at it also dropping the macros previously used, not reusing it
to improve readability.

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.
