Juno/vexpress/FVP kernel based on latest version of Linux (v4.5)

Changes in this version:
- Update Base FVP device-trees for GICv3 and make them more accurate to
  latest models. New name for device-tree is fvp-base-aemv8a-aemv8a.dts
  (old name was fvp-base-gicv2-psci.dts).
- Update Foundation FVP device-trees from linux-next and drop our
  versions. Name is now foundation-v8-gicv3.dts rather than
  fvp-foundation-gicv2-psci.dts.
- Proper pl330 dma driver fix to get audio working on Android.

Issues:
- Foundation Model device-trees are lacking 'mcc' node for
  'arm,vexpress,config-bus' so poweroff and reboot don't work.
