Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150908' into staging

target-arm queue:
 * Implement priority handling properly via GICC_APR
 * Enable TZ extensions on the GIC if we're using them
 * Minor preparatory patches for EL3 support
 * cadence_gem: Correct Marvell PHY SPCFC reset value
 * Support AHCI in ZynqMP
