Remove trailing spaces and TABs.

Make sure to specify volatile explicitly on DMA register accesses.

It looks booting from SCSI disks on next68k have been broken
since NetBSD 1.6 days, but now it works.

Avoid possible division by zero trap in error cases to make debug easier.

Request only 36 bytes for a response of INQUIRY command for legacy drives.
Some drives don't respond larger requested size for newer
SCSI3 devices and not all drivers can handle short xfers.
We should fix drivers to handle such short xfers properly,
but we need only SCSI device type here (and the 36 bytes are
enough even if we want vendor and product names on a bootloader).
The problem is reported from Andreas Grabher (a maintainer of NeXT
Computer Emulator) on port-next68k@:
 https://mail-index.netbsd.org/port-next68k/2023/02/thread1.html

Disable DEBUG options properly.

Bump version to 1.6 to denote recent bootloader's >20 years old bug fixes.
