hw/dma: Move ScatterGatherEntry / QEMUSGList declarations around

Browse Source 
In the next commit we will use the dma_addr_t type in the QEMUSGList
structure. Since currently dma_addr_t is defined after QEMUSGList,
move the declarations to have dma_addr_t defined first. This is a
pure code-movement patch.
