Some systems compile in both ARMv6 and ARMv7 into multiplatform
configurations. This means the default compiler flags are for ARMv6,
and we will get:
arch/arm/mach-mvebu/coherency_ll.S: Assembler messages:
arch/arm/mach-mvebu/coherency_ll.S:45: Error: selected processor does not support `dsb'
Fix this by specifying ARMv7 flags for coherency_ll.o.

Applied to fixes, I don't expect Jason or others to complain about this
so I took the liberty. :)
