mpi3mr: Validating SAS port assignments

Sanity on phy_mask was added by Tomas through [1].
It causes warning messages when >64 phys are
detected (expander can have >64 phys) and devices
connected to phys greater than 64 are dropped.
phy_mask bitmap is only needed for controller
phys(not required for expander phys).Controller phys
can go maximum up to 64 and u64 is good enough to contain phy_mask bitmap.

To suppress those warnings and allow devices to be discovered as before the [1], restrict the phy_mask setting and lowest phy setting only to the controller phys.
