Host1x command buffer patching requires that the buffer object can be
mapped into kernel address space, however, the recent addition of
IOMMU did not account to this requirement. Therefore Host1x engines
cannot be used if IOMMU is enabled.

This patch implements kmap, kunmap, mmap and munmap functions to
host1x bo objects.

Applied with a tiny fixup of the commit message, thanks.
