ide: Update ide_drive_get to be HBA agnostic
Instead of duplicating the logic for the if_ide (bus,unit) mappings, rely on the blockdev layer for managing those mappings for us, and use the drive_get_by_index call instead. This allows ide_drive_get to work for AHCI HBAs as well, and can be used in the Q35 initialization. Lastly, change the nature of the argument to ide_drive_get so that represents the number of total drives we can support, and not the total number of buses. This will prevent array overflows if the units-per-default-bus property ever needs to be adjusted for compatibility reasons.
