Subject: [PATCH] netdev/phy: Make get_phy_id() static and quit EXPORTing it.

From: David Daney <david.daney@...ium.com>

This function is only referenced from within phy_device.c, so there is
no reason to export it.  In fact, we can make it static.

Signed-off-by: David Daney <david.daney@...ium.com>
