MINIMAL: Grow minimal to support ata, scsi and nvme
Until the boot loader automatically loads these things (including the
CAM dependency), we need to have them in the minimal kernel since they
are needed to boot. These aren't strictly required to be in the kernel,
since modules work, but are high enough demand items that until we sort
out boot loader automation, I'm adding them here. These devices are also
common in vm environments. The delta is relatively small in size. Once
the boot loader automation arrives, these and a lot of other things can
be trimmed. It's less than ideal, but is a good middle ground for the
moment.
