Pull up following revision(s) (requested by msaitoh in ticket #649):

        sys/dev/mii/ihphy.c: revision 1.15

 Remove extra 10ms delay in ihphy_reset(). The delay are in if_wm.c side.
It's required for hardware full reset and it't not requred on soft reset.

 When ihphy.c was added in 9 years ago, some workaround code were not in
if_wm.c yet and the initialization code was not good.
