iommu/omap: Use BIT(x) macros in omap-iommu.h
Switch to using the BIT(x) macros in omap-iommu.h where possible. This eliminates the following checkpatch check warning: "CHECK: Prefer using the BIT macro" A couple of the warnings were ignored for better readability of the bit-shift for the different values.
