Andy Shevchenko af6c7e1ffc platform/x86: intel_pmc_ipc: Don't map non-used optional resources
The intel_pmc_ipc driver has a placeholder for all possible resources
that may have been provided by ACPI. Since there are few optional ones,
the driver still uses them and binds to wrong ranges in resource tree:

  # grep intel_punit_ipc /proc/iomem
  00000000-00000000 : intel_punit_ipc
    00000000-00000000 : intel_punit_ipc
      00000000-00000000 : intel_punit_ipc
        00000000-00000000 : intel_punit_ipc

This leads to issues with resource management during inserting and
removing modules, such as intel_pmc_ipc itself, which can't be inserted
anymore after first removal.

Count the actual resources provided and supply only them to the child device.

This is a real fix of the commit 8cc7fb4a65

  ("intel_pmc_ipc: update acpi resource structure for Punit")

that also fixes a symptoms described in the commit 6cc8cbbc88

  ("platform/x86: intel_punit_ipc: Fix resource ioremap warning")

that is going to be reverted afterwards.

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.
