Add softraid(4) RAID 1C boot support
Equivalent of sys/arch/arm64/stand/efiboot/softraid_arm64.c r1.4:
(commitid: Ka484R3swI5xSRWO) "Add softraid(4) RAID 1C boot support".
Tell the boot loader to decrypt 1C like C volumes and check the number of
disks in 1C like in 1C volumes -- no new code rquired.
Tested on T4-2 guest domains
"Looks reasonable" kettenis
OK stsp
NB: While kernel and boot loader support root on softraid on sparc64,
installboot(8) still needs a pending fix for installations on multi-chunk
softraid volumes. Until then, the usual installation process will fail on
1C volumes and requires manual fixup.
