[PATCH net-next 4/8] tg3: Relax 5717 serdes restriction

["Matt Carlson" <mcarlson@broadcom.com>]

tg3 is coded to refuse to attach to 5717 serdes devices.  Now that the
hardware is better supported, we can relax this restriction.  This patch
also fixes a recently introduced bug which will cause serdes parallel
detection not to work with 5780 class devices.
