PCI/ASPM: Enable ASPM for links under VMD domain

New Intel laptops with VMD cannot reach deeper power saving state,
renders very short battery time.

As BIOS may not be able to program the config space for devices under
VMD domain, ASPM needs to be programmed manually by software. This is
also the case under Windows.

The VMD controller itself is a root complex integrated endpoint that
doesn't have ASPM capability, so we can't propagate the ASPM settings to
devices under it. Hence, simply apply ASPM_STATE_ALL to the links under
VMD domain, unsupported states will be cleared out anyway.

lib: Revert use of fallthrough pseudo-keyword in lib/

The following build error for powerpc64 was reported by Nathan Chancellor:

  "$ scripts/config --file arch/powerpc/configs/powernv_defconfig -e KERNEL_XZ

   $ make -skj"$(nproc)" ARCH=powerpc CROSS_COMPILE=powerpc64le-linux- distclean powernv_defconfig zImage
   ...
   In file included from arch/powerpc/boot/../../../lib/decompress_unxz.c:234,
                    from arch/powerpc/boot/decompress.c:38:
   arch/powerpc/boot/../../../lib/xz/xz_dec_stream.c: In function 'dec_main':
   arch/powerpc/boot/../../../lib/xz/xz_dec_stream.c:586:4: error: 'fallthrough' undeclared (first use in this function)
     586 | fallthrough;
         | ^~~~~~~~~~~

   This will end up affecting distribution configurations such as Debian
   and OpenSUSE according to my testing. I am not sure what the solution
   is, the PowerPC wrapper does not set -D__KERNEL__ so I am not sure
   that compiler_attributes.h can be safely included."

In order to avoid these sort of problems, it seems that the best
solution is to use /* fall through */ comments instead of the
fallthrough pseudo-keyword macro in lib/, for now.

Merge tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux

Pull 'fallthrough' keyword conversion from Gustavo A. R. Silva:
 "A tree-wide patch that replaces tons (2484) of /* fall through */
  comments, and its variants, with the new pseudo-keyword macro
  fallthrough[1]. Also, remove unnecessary fall-through markings when it
  is the case.

  There are currently 1167 intances of this fallthrough pseudo-keyword
  macro in mainline (5.9-rc2), that have been introduced over the last
  couple of development cycles:

    $ git grep -nw 'fallthrough;' | wc -l
    1167

  The global adoption of the fallthrough pseudo-keyword is something
  certain to happen; so, better sooner than later. :) This will also
  save everybody's time and thousands of lines of unnecessarily
  repetitive changelog text.

  After applying this patch on top of 5.9-rc2, we'll have a total of
  3651 instances of this macro:

    $ git grep -nw 'fallthrough;' | wc -l
    3651

  This treewide patch doesn't address ALL fall-through markings in all
  subsystems at once because I have previously sent out patches for some
  of such subsystems separately, and I will follow up on them; however,
  this definitely contributes most of the work needed to replace all the
  fall-through markings with the fallthrough pseudo-keyword macro in the
  whole codebase.

  I have build-tested this patch on 10 different architectures: x86_64,
  i386, arm64, powerpc, s390, sparc64, sh, m68k, powerpc64 and alpha
  (allyesconfig for all of them). This is in linux-next already and
  kernel test robot has also helped me to successfully build-test early
  versions of this patch[2][3][4][5]"
