dma: Let dma_memory_read/write() take MemTxAttrs argument

Let devices specify transaction attributes when calling
dma_memory_read() or dma_memory_write().

Patch created mechanically using spatch with this script:

  @@
  expression E1, E2, E3, E4;
  @@
  (
  - dma_memory_read(E1, E2, E3, E4)
  + dma_memory_read(E1, E2, E3, E4, MEMTXATTRS_UNSPECIFIED)
  |
  - dma_memory_write(E1, E2, E3, E4)
  + dma_memory_write(E1, E2, E3, E4, MEMTXATTRS_UNSPECIFIED)
  )
