[5/7] hw/ide: Move IDE DMA related definitions to a separate header ide-dma.h

These definitions are required outside of the hw/ide/ code, too,
so lets's move them from internal.h to a new header called ide-dma.h.

Doesn't this need to #include something to define QEMUIOVector and 
BlockAIOCB and some of the DMA and IDE types not defined above?

Yes, it currently works by accident since the header is only included in 
spots where those things are already defined, but I'll better add some 
#include statements here so that this header can also be used stand-alone in 
other spots.
