Subject: [PATCH] omap: iommu: fix pte attributes for super section
The PTE programming causes a 16MB entry to be interpreted
as a 4K entry because of the bitwise check, and therefore does
not set the attributes properly in the first-level descriptor
table. The bitwise check has been replaced appropriately.
