[PATCH v3] docs: arm64: Fix typo "initalised" in booting.rst

[Hemanth Selam <hemanth.selam@gmail.com>]

Add the missing "i" to "initalised" in the description of the
spin-table cpu-release-addr property.

The British spelling is deliberate.  doc-guide/contributing.rst asks
that both American and British spellings be left alone, so only the typo
is corrected, not the dialect.  checkpatch.pl suggests "initialized"
here because scripts/spelling.txt maps this entry to the American form;
that is addressed separately.

Notes:
    Changes since v2:
     - the guidance lives in doc-guide/contributing.rst, not
       doc-guide/checkpatch.rst as v2 claimed (Weijie Yuan)
     - drop the v1 narrative and the redundant "only the documentation text
       changes" line
    
    Changes since v1:
     - keep "initialised" rather than switching the file to "initialized",
       so the British spelling is preserved (Randy Dunlap)
