[Qemu-trivial] [PATCH] target-arm: Fix typos in comments

[Peter Maydell]

Fix a variety of typos in comments in target-arm files.

Signed-off-by: Peter Maydell <address@hidden>
---
Includes all the ones I spotted but not the 'middel' fix which
Peter C has already submitted a patch for, so the two patches
shouldn't conflict.
