ARM: 7484/1: Don't enable GENERIC_LOCKBREAK with ticket spinlocks
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.
