Subject: hw/dma: Use dma_addr_t type definition when relevant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Update the obvious places where dma_addr_t should be used
(instead of uint64_t, hwaddr, size_t, int32_t types).
This allows to have &dma_addr_t type portable on 32/64-bit
hosts.
