Properly alphabetize MAINTAINERS file

This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.

My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a
perl script.

platform/x86: intel_pmc_core: Remove unused header file

Recently sent patch 'platform/x86: intel_pmc_core: Remove unused EXPORTED
API' missed to remove the header file 'arch/x86/include/asm/pmc_core.h'
which was solely used to declare the EXPORTED API
'intel_pmc_slp_s0_counter_read'. This patch provides the errata fix for the
same.

This is strange the shuffle of the MAINTAINERS based on the script is
a culprit of the above inconsistency.

Btw, I run parse-maintainers.pl against it and there are a lot more
"unsorted" lines.
What Linus or me or both did miss?

Nothing really.

The script used git-blame on the specific line, that's all.

There is no simple way to actually find a specific
commit that adds a particular line to a file if there is
any refactoring done to the file after it was added.

platform/x86: Add PMC Driver for Intel Core SoC

Anyway, the real cause of the file pattern being unused
was also written below:
