dmaengine: mmp: Fix again Wvoid-pointer-to-enum-cast warning

This was fixed and re-introduced.  'type' is an enum, thus cast of
pointer on 64-bit compile test with W=1 causes:

  mmp_tdma.c:644:9: error: cast to smaller integer type 'enum mmp_tdma_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
