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 The motivation for this change is a recent DEBUG_AHCI build failure due to an outdated DPRINTF() format string.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.
