Tweak the DC_REDUCED_MII_POLL code in dc_mii_tick() for the DC_IS_INTEL()

case. The idea is to reduce how often we call mii_tick(), however currently
it may not be called often enough, which prevents autonegotiation from
being driven correctly.

This should improve the chances of successfully autonegotiating media
settings on non-MII 21143 NICs. (Still waiting for confirmation from
some testers, but the code is clearly wrong in any case.)
