Now that ARM has implemented its spinlocks with tickets we don't
need to use the generic lockbreak algorithm. Remove the Kconfig
from ARM so that we use the arch_spin_is_contended() definition
from the asm header. This also saves a word in each lock because
we don't need the break_lock member anymore.

It seems we define the arch_spin_is_contended() macro but we don't
use it on SMP && PREEMPT kernels?
