Add option HD64461PCMCIA_REORDER_ATTACH that attaches channels in

reversed order.

When you boot with two CF cards inserted, this options makes the one
in the "memory only" slot (channel 1), which is almost always the card
with the NetBSD install, attached as wd0.

Unlike using fixed unit numbers in the kernel config, if you boot with
only a single CF card, that single card will still be wd0 regardless
of which slot it is inserted in.

http://mail-index.netbsd.org/port-hpcsh/2003/10/23/0000.html provides
a more verbose description of why this option is convenient for most
usage patterns.
