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.
