  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')

Cc: akhil.goyal@nxp.com

V2: use "ms->addr" instead of  "(void *)ms->addr_64" to fix
    compilation on 32bit (i686)
