ahci: avoid #ifdef DEBUG_AHCI bitrot
Debug code using #ifdef is susceptible to bitrot because the compiler
never checks the debug code.
This is easy to avoid, change the DPRINTF() macro to use if (DEBUG_AHCI)
and always give it a 0 or 1 value.
This also allows us to drop an #ifdef DEBUG_AHCI in ahci_start_dma()
since the compiler can now see the local variable is used.
The motivation for this change is a recent DEBUG_AHCI build failure due
to an outdated DPRINTF() format string. From now on the compiler will
catch these errors.
