Paolo Bonzini ae79c2db15 ahci: fix FIS I bit and PIO Setup FIS interrupt 
The "I" bit in PIO Setup and D2H FISes is exclusively a device concept
and the irqstatus register in the controller does not matter.  The SATA
spec says when it should be one; for D2H FISes in practice it is always
set, while the PIO Setup FIS has several subcases that are documented in
the patch.

Also, the PIO Setup FIS interrupt is actually generated _after_ data
has been received.

Someone should probably spend some time reading the SATA specification and
figuring out the more obscure fields in the PIO Setup FIS, but this is enough
to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.
