Save extended address register prior to switching to 1000BASE-X

Browse source 
only mode and restore original value of extended address register
instead of overwriting it with page 1. There are still instance
information passing issue(e.g configured media type: fiber or
copper) from driver to PHY layer but this change make the selected
PHY work with 88E1112 PHY.
