iommu/omap: Fix cache flushes on L2 table entries
[ Upstream commit 04c532a1cdc7e423656c07937aa4b5c1c2b064f9 ]
The base address used for DMA operations on the second-level table
did incorrectly include the offset for the table entry. The offset
was then added again which lead to incorrect behavior.
Operations on the L1 table are not affected.
The calculation of the base address is changed to point to the
beginning of the L2 table.
