The value of 2 can't fit in a 1 bit wide field.

The phy_speed_100mbs, phy_full_duplex, and phy_link_active fields of
PHY_STATUS_TYPE are 1 bit wide but lpc_phy_init() attempted to
initialize them to a value of 2.  I switched the initializations to
be 0 instead and it still generated the same .bin image.
