Pull up following revision(s) (requested by gson in ticket #179):
sys/dev/ata/satafis_subr.c: revision 1.9
Set the ATAPI "BYTE COUNT LIMIT" field in the SATA case like we
already do in the ATA case, to make NetBSD work with the virtual
SATA CD-ROM of "qemu-system-i386 -machine q35". Fixes PR kern/54389.
OK mlelstv.
