[PATCH v2] docs: arm64: Fix typo "initalised" in booting.rst

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

Correct the misspelling "initalised" in the arm64 booting document.

v1 changed it to "initialized", which quietly moved the file from
British to American spelling.  Randy Dunlap pointed out that
doc-guide/checkpatch.rst asks that both spellings be left alone, so
this uses "initialised" and only fixes the missing "i".

checkpatch.pl suggested "initialized" because scripts/spelling.txt maps
these two entries to the American form; that is addressed separately.

Only the documentation text changes.
