Based on ews4800mips, mvme68k, and x68k standalone drivers.
Also bump version.

Tested on LUNA-I.

XXX: We really need proper documents about libsa APIs.

Tested on only LUNA-I for now.
 1.2  10-Jan-2013  tsutsui Use proper asm symbol macro.
 1.1  05-Jan-2013  tsutsui First cut at NetBSD/luna68k native bootloader.

Based on 4.4BSD-Lite2/luna68k "Stinger" loader revision "Phase-31"
http://svnweb.freebsd.org/csrg/sys/luna68k/stand/
and MI libsa glue stuff are taken from hp300 etc.

Tested on LUNA-I and old DK315C SCSI disk drive.

LUNA's monitor PROM can load only an a.out binary in 4.3BSD FFS partition
(i.e. created by "newfs -O 0") on disks with OMRON's UniOS disklabel,
but now we can load an ELF kernel in root partition via this bootloader.
(See luna68k/disksubr.c for details of UniOS label)

TODO:
- LUNA-II support (check 68040 to adjust cpuspeed for DELAY())
- secondary SCSI support for LUNA-II
- netboot via le(4) (should be trivial)
- support boot options on bootloader prompt
- bootinfo (passing info about booted device and kernel symbols)
- support "press return to boot now, any other key for boot menu" method
like x86 bootloader (needs cnscan() like functions)
- tapeboot (anyone wants it?)
