MFC 265694, 265705, 265784:
Move the mptramp code which is specific to the Marvell ArmadaXP SoC out of the common locore.S file and into the mv/armadaxp directory. Consolidate all the AP core startup stuff under a single #ifdef SMP block Call idcache_inv_all from the AP core entry code before turning on the MMU. Also, enable instruction and branch caches, which should be safe now that they're properly initialized/invalidated first.
