scsi: pm80xx: Update PHY state after hard reset

Browse source 
Update phy_attached, phy_state, and port_state to correct values after a
hard rest. Without this patch, after a successful hard reset, phy_attached
is still 0, as a result, any following hard reset will cause a PHY START to
be issued first.
