Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20141024' into staging

target-arm queue:
 * remove pointless 'info pcmcia' and a lot of now-dead code
 * register ARM cpu reset handlers even if not using -kernel
 * update to libvixl 1.6
 * various minor code cleanups
 * support PSCI under TCG ('virt' machine can now be shut down,
   SMP configurations work)
 * correct the sense of the AArch64 DCZID DZP bit
 * report a valid L1Ip field in CTR_EL0 for CPU type "any"
 * correctly UNDEF writes to FPINST/FPINST2 from EL0
 * more preparatory code refactoring for EL2/EL3 support
