ARM: 8427/1: dma-mapping: add support for offset parameter in dma_mmap()

IOMMU-based dma_mmap() implementation lacked proper support for offset
parameter used in mmap call (it always assumed that mapping starts from
offset zero). This patch adds support for offset parameter to IOMMU-based
implementation.
