dma: Let dma_memory_map() take MemTxAttrs argument

Let devices specify transaction attributes when calling
dma_memory_map().

Patch created mechanically using spatch with this script:

  @@
  expression E1, E2, E3, E4;

  - dma_memory_map(E1, E2, E3, E4)
  + dma_memory_map(E1, E2, E3, E4, MEMTXATTRS_UNSPECIFIED)
