Ankit Nautiyal 5947642004 drm/i915/display: Add support for SNPS PHY HDMI PLL algorithm for DG2
Add helpers to calculate the necessary parameters for configuring the
HDMI PLL for SNPS MPLLB and C10 PHY.

The pll parameters are computed for desired pixel clock, curve data
and other inputs used for interpolation and finally stored in the
pll_state.

Currently the helper is used to compute PLLs for DG2 SNPS PHY.
Support for computing Plls for C10 PHY is added in subsequent patches.

v2:
-Used kernel types instead of C99 types. (Jani)
-Fixed styling issues and renamed few variables to more meaningful
 names. (Jani)
-Added Xe make file changes. (Jani)
-Fixed build errors reported by kernel test robot

v3:
-Renamed helper to align with file name. (Jani)

v4:
-Removed erroraneous comment, and added Bspec# as part of trailer. (Suraj)
-Fixed warning flagged by kernel test robot.

Bspec: 54032

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 reStructuredText 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.
