xen/arm: WORKAROUND 1:1 memory mapping for dom0

Currently xen doesn't implement SYS MMU. When a device will talk with dom0
with DMA request the domain will use GFN instead of MFN.
For instance on the arndale board, without this patch the network doesn't
work.

The 1:1 mapping is a workaround and MUST be remove as soon as a SYS MMU is
implemented in XEN.
