iommu/msm: Fix error handling in msm_iommu_unmap()
Error handling in msm_iommu_unmap() is broken. On some error
conditions retval is set to a non-zero value which causes
the function to return 'len' at the end. This hides the
error from the user. Zero should be returned in those error
cases.

iommu/msm: announce supported page sizes
Let the IOMMU core know we support 4KiB, 64KiB, 1MiB and 16MiB page sizes.
This way the IOMMU core can split any arbitrary-sized physically
contiguous regions (that it needs to map) as needed.

iommu/core: stop converting bytes to page order back and forth
Express sizes in bytes rather than in page order, to eliminate the
size->order->size conversions we have whenever the IOMMU API is calling
the low level drivers' map/unmap methods.
Adopt all existing drivers.

iommu/msm: ->unmap() should return order of unmapped page
Users of the IOMMU API (kvm specifically) assume that iommu_unmap()
returns the order of the unmapped page (on success).
Fix msm_iommu_unmap() accordingly.

msm: iommu: move to drivers/iommu/
This should ease finding similarities with different platforms,
with the intention of solving problems once in a generic framework
which everyone can use.
Compile-tested for MSM8X60.
