net: ethernet: Fix up drivers masking pause support

lunn · davem330 · commit 04b7d41d8046 · 2018-09-12T20:24:21.000-07:00
PHY drivers don't indicate they support pause. They expect MAC drivers
to enable its support if the MAC has the needed hardware. Thus MAC
drivers should not mask Pause support, but enable it.

Change a few ANDs to ORs.
