net: phy: fixed_phy: Set phy capabilities even when link down.

What features a phy supports is masked in genphy_config_init() by
looking at the PHYs BMSR register.

If the link is down, fixed_phy_update_regs() will only set the auto-
negotiation capable bit in BMSR. Thus genphy_config_init() comes to
the conclusion the PHY can only perform 10/Half, and masks out the
higher speed features. If however the link it up, BMSR is set to
indicate the speed the PHY is capable of auto-negotiating, and
genphy_config_init() does not mask out the high speed features.

To fix this, when the link is down, have fixed_phy_update_regs() leave
the link status, auto-negotiation complete, and link partner
capabilities unset, but set all the local capabilities depending on
the fixed phy speed.
