Subject: [PATCH] arm,arm64: do not always merge biovec if we are running on
 Xen

This is similar to what it is done on X86: biovecs are prevented from merging
otherwise every dma requests would be forced to bounce on the swiotlb buffer.

Acked-by: Catalin Marinas <catalin.marinas@arm.com>


Changes in v7:
