locks: linker variables to calculate per-cpu bakery lock size
This patch introduces explicit linker variables to mark the start and
end of the per-cpu bakery lock section to help bakery_lock_normal.c
calculate the size of the section. This patch removes the previously
used '__PERCPU_BAKERY_LOCK_SIZE__' linker variable to make the code
uniform across GNU linker and ARM linker.
