MCP5x family of controllers seem to share much more with nf2's as far
as reset protocol is concerned.  It requires heardreset to get the PHY
going and classfication code report after hardreset is unreliable.
Create a new board type MCP5x and use noclassify hardreset.  SWNCQ is
modified to inherit from this new type.

This fixes hotplug regression reported in kernel bz#12351.
