[PATCH 1/4] Documentation/arch: fix typo "initalised" in comment

[Hemanth Selam]

Thanks for the pointer, and you are right to raise it - I checked and this
patch does fall foul of that rule.

The word in Documentation/arch/arm64/booting.rst is "zero-initalised", and
I changed it to "zero-initialized", which quietly moves the file from
British to American spelling.  The minimal fix is "zero-initialised".

I followed checkpatch here, and checkpatch is following the dictionary:

  scripts/spelling.txt:875:initalised||initialized
  scripts/spelling.txt:874:initalise||initialize

Those are the only two entries in the file that map a British form to an
American one, and by the rule you quoted they should read

  initalise||initialise
  initalised||initialised

so that the misspelling is corrected without changing the variety of
English in the file.  arch/arm64 currently has 58 uses of "initialised"
against 132 of "initialized", so both spellings are clearly in use there.

I will send a v2 that uses "zero-initialised".  Would a separate patch
fixing those two spelling.txt entries be welcome, or is that better left
alone?
