dpaa_sec needs translations between physical and virtual addresses. V to P
translation is relatively fast, as memory is managed in contiguous segments.
The result of each V to P translation is used to update the DPAA iova table,
which should be updated by a Mem event callback, but is not.
Then the DPAA iova table has entries for all needed memory ranges.
With this patch, dpaa_mem_ptov will always use dpaax_iova_table_get_va, which
ensures optimal performance.
Fixes: 5a7dbb934d75 ('dpaa: enable dpaax library')
