[ upstream commit a9aa14d ]

Fix spelling errors in comments (found with codespell).

Note that "inbetween" is not correct in English and should
either be two words or better yet, the in can be dropped.

Fixes: 12f45fa ("eal/arm: read timer from PMU if enabled")
Fixes: 096ffd8 ("eal/x86: use lock-prefixed instructions for SMP barrier")
Fixes: 1d40645 ("mem: make segment preallocation OS-specific")
Fixes: bb37206 ("malloc: make heap a doubly-linked list")
Fixes: 7353ee7 ("fbarray: add API to find biggest used or free chunks")
