New device names for "mass"

[rickgaiser]

This PR adds new device names for BDM devices so we can separate them and load the appropriate drivers when we know the path. The following have been created:

• atad: "ata"
• usbmass_bd: "usb"
• mx4sio_bd: "mx4sio"
• IEEE1394_bd: "ilink"

The old "mass:" is still present for compatibility, but new software should use "usb:", "ata:", "mx4sio:" and "ilink:" instead.

I think it's good to have a discussion about the appropriate names first.

edit: changed "hdd" to "ata"

I feel using hdd: for exFAT HDD partitions is not a good idea because it might conflict with hdd0: and hdd1: used by APA modules. For example, NHDDL and OSDMenu Configurator load BDM and APA modules at the same time to support APA Jail setups.
Maybe just call it ata instead?

Good point, I was having issues in neutrino as well becouse it's names "ata" everywhere. I changed it.

Personally to me ATA is still ambiguously close to APA simply because PS2 IS ATA for both. However I do feel APA should stay as hdd?:/ for APA

I am unsure really what to call block device hdd stuff....
