Recent SoC such as Armada 370/XP came with the possibility to deal
with the I/O coherency by hardware. In this case the transaction
attribute of the window must be flagged as "Shared transaction". Once
this flag is set, then the transactions will be forced to be sent
through the coherency block, in other case transaction is driven
directly to DRAM.

The functions for address mapping management now take void __iomem
pointers, so we remove the temporary "unsigned long" casts from the
mach-*/common.c files.

Use an getter function in plat-orion/addr-map.c to get the address map
structure, rather than pass it to drivers in the platform_data
structures. When the drivers are built for none orion platforms, a
dummy function is provided instead which returns NULL.
