Log Message:
Pull up following revision(s) (requested by tsutsui in ticket #1617):
        sys/arch/x68k/dev/fd.c: revision 1.94 via patch
Fix hangup on the first floppy access since 2008.
Problem was reported by isaki@.
On X680x0 (and most other machines other than ISA FDC),
the ready line from FDD is connected to FDC and fdc driver can
be notified of the ready state after fd_set_motor() by interrupts.
In this case no need to use callout(9) to wait the FDD motor stabilized,
and the callout(9) method used in ISA fdc(4) driver rather caused
infinite unhandled interrupts since callout(9) was no longer invoked
during interrupt storm after vmlocking2 merge, I guess.
Should be pulled up to netbsd-5.
