Add new priority checker mpath_hp_sw

All paths from a controller with HP Active/Standby firmware should really be grouped according to their status; otherwise the path switching will not work properly or you can use only one path to that array.
This patch adds a new priority checker 'mpath_hp_sw' which will allow these paths to be grouped accordingly.
