	src/sys/dev/ic: wdc.c

Log Message:
Remove the "Register ghost test". It won't work, because on ATA register
of both devices are written, and device 0 will respond for device 1 if
device 1 isn't present. Pointed out by Quentin Garnier.
So the only way to know if device 1 is there or not is to send a command, which
is done later.
Detecting the second device here isn't important and won't speed up the probe.
We just need to know if there is at last one device on the bus.

Fix PR kern/22869 from Julio M. Merino Vidal.
