Add Raspberry Pi 2 support

Detail:
  The Raspberry Pi ROM now joins the IOMD ROM in supporting multiple
  architectures, in this case ARMv6 and ARMv7. This has been achieved by
  creating a new machine type specific for Raspberry Pi. The old ARM11ZF
  machine type remains for builds that are ARM11-only.

Version 6.64. Tagged as 'BuildSys-6_64'
