Fix assert in bakery_lock_release() ...

bakery_lock_release() expects an mpidr as the first argument however
bakery_lock_release() is calling it with the 'entry' argument it has
calculated. Rather than fixing this to pass the mpidr value it would be
much more efficient to just replace the call with

   assert(bakery->owner == entry)

As this leaves no remaining users of bakery_lock_held(), we might as
well delete it.

Fixes ARM-software/tf-issues#27

Change comments in assembler files to help ctags ...

Ctags seem to have a problem with generating tags for assembler symbols
when a comment immediately follows an assembly label.

This patch inserts a single space character between the label
definition and the following comments to help ctags.

The patch is generated by the command:

  git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1'
