Matt Roper e8ab8d669d drm/i915/ehl: Define EHL powerwells independently of ICL
Outputs C and D on EHL are combo PHY outputs and thus should not be
using the same TC AUX power well handlers as ICL.  And even though
icl_combo_phy_aux_power_well_ops works okay for EHL/JSL combo PHYs none
of its special handling is actually necessary for this platform:
 * EHL/JSL don't actually need to program PORT_CL_DW12
 * Display WA #1178 does not apply to EHL/JSL

Thus we can simply drop back to using our standard "hsw-style" power
well ops for EHL AUX power wells.

Fixes: f722b8c1e2 ("drm/i915/ehl: All EHL ports are combo phys")

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.
