Add an "inline" so the compiler no longer gives a defined-but-not-used
warning.

Ensure that on detach any lazy mappings for that device are released.
We don't want to leave any outstanding mappings after detach because
the client expects all mappings to have been unmapped, also we don't
want to leave references, in the lazy mapping framework, to devices
which could cease to exists.

Allow compilation when CONFIG_ARM_DMA_USE_IOMMU is not
selected by providing necessary stub functions and fix few
mismatch in function declarations.
Following this, remove the changes introduced by
f3d8d1061fb0b146b3f5 ("msm: ipa: add empty implementation
for iommu functions") as they are no longer needed.

The msm lazy mapping APIs did not allow to pass in
dma attributes that could be passed to the dma-mapping
driver. This patch allows users to specify dma attributes for the
msm lazy mappings.

Make all msm_dma_iommu apis depend on CONFIG_IOMMU_API as it is
only used when we have the linux iommu layer available.

Add new APIs to allow clients to map and unmap dma_buffers created by
ION. The call to the unmap API will not actually do the unmapping from the
IOMMU. The unmapping will occur when the ION/dma_buf buffer is actually
freed. This behavior can be disabled with DMA_ATTR_NO_DELAYED_UNMAP
