This extends the --gc-sections behaviour to the many assembler
support functions in the firmware images by placing each function
into its own code section. This is achieved by creating a 'func'
macro used to declare each function label.

Current implementation of Bakery Lock does tight-loop waiting upon lock
contention.
This commit reworks the implementation to use WFE instruction for
waiting, and SEV to signal lock availability. It also adds the rationale
for choosing Bakery Locks instead of exclusion primitives, and more
comments for the lock algorithm.

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.

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'
