Dario Faggioli 1c1a7cdd40 qemu: Add support for max physical address size
This patch maps /domain/cpu/maxphysaddr into -cpu parameters:

  - <maxphysaddr mode='passthrough'/> becomes host-phys-bits=on
  - <maxphysaddr mode='emualte' bits='42'/> becomes phys-bits=42

Passthrough mode can only be used if the chosen CPU model is
'host-passthrough'. Also validate that an explicitly specified
bits value does not exceed the physical address bits on the host.

The feature is available since QEMU 2.7.0.
