 Don't try to read disklabel to check FS_RAID on floppy boot since
 reopening floppy could cause Data Access Exception later.
 Fixes PR port-sparc/42186, ok'ed by mrg@.
 Use /dev/fd0a rather than /dev/rfd0a to read instfs.tgz image from floppy.
 It looks newer (appearred after 1.6) gzip tries to read less than DEV_BSIZE
 (to check header?) so we can't use raw device directly.
 (note sparc bootfs ramdisk doesn't have dd(1))
 Workaround for PR port-sparc/42193, and would also fix PR install/28734.
 Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
 pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
 A comment in the macro says AUXIO4M_FTC bit is auto-clear,
 but my two SS20s (including compatible) with 150MHz hyperSPARCs
 get data_overrun without it, and no bad side effect on SS5
 (works with and without this change).
 Closes PR port-sparc/42516, which is the last one of a bunch of
 floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
 for details.
