[PATCH v2 3/6] pch_gbe: change order of PHY address discovering

[Alexander Stein <alexander.stein@systec-electronic.com>]

From: Daniel Krueger <daniel.krueger@systec-electronic.com>

Scan PHY address 0 after all other addresses. Address 0 is a multicast
address which unfortunately does not work properly with Micrel KSZ9021.
Our board uses PHY address 2.
