Precede a 'sev' with a 'dsb' in bakery lock code
This patch fixes a bug in the bakery lock implementation where a data synchronisation barrier instruction is not issued before sending an event as mandated by the ARMv8 ARM. This can cause a event to be signalled before the related memory accesses have completed resulting in erroneous execution. Fixes ARM-software/tf-issues#272 Change-Id: I5ce02bf70afb001d967b9fa4c3f77442931d5349
