Similarly to the previous patch use a separate request/status HW flag index defined right after the corresponding control registers instead of depending for this on the power well IDs. Since the set of control/status registers varies among the different power wells (on a single platform), also add a new i915_power_well_registers struct that we populate and assign to each DDI power well as needed. Also clarify a bit the code comment describing the function and layout of the control registers. This also fixes a problem on ICL, where we incorrectly read the KVMR control register in hsw_power_well_requesters() even for DDI and AUX power wells. v2: - Clarify platform range tags in code comments. (Paulo) - Fix line over 80 chars checkpatch warning.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
