Greg Ungerer 2667677fb8 bus: mvebu: pass the coherency availability information at init time 
commit 5686a1e5aa upstream.

Until now, the mvebu-mbus was guessing by itself whether hardware I/O
coherency was available or not by poking into the Device Tree to see
if the coherency fabric Device Tree node was present or not.

However, on some upcoming SoCs, the presence or absence of the
coherency fabric DT node isn't sufficient: in CONFIG_SMP, the
coherency can be enabled, but not in !CONFIG_SMP.

In order to clean this up, the mvebu_mbus_dt_init() function is
extended to get a boolean argument telling whether coherency is
enabled or not. Therefore, the logic to decide whether coherency is
available or not now belongs to the core SoC code instead of the
mvebu-mbus driver itself, which is much better.

[ Greg Ungerer: back ported to linux-3.10.y
  Back port necessary due to large code differences in affected files.
  This change in combination with commit e553554536 ("ARM: mvebu: disable
  I/O coherency on non-SMP situations on Armada 370/375/38x/XP") is
  critical to the hardware I/O coherency being set correctly by both the
  mbus driver and all peripheral hardware drivers. Without this change
  drivers will incorrectly enable I/O coherency window attributes and
  this causes rare unreliable system behavior including oops. ]
