net: phy: at803x: move page selection fix to config_init

[ Upstream commit 4f3a00c7f5b2cfe4e127fd3fe49b55e1b318c01f ]

The fix to select the copper page on AR8031 was being done in the probe
function rather than config_init, so it would not be redone after resume
from suspend. Move this to config_init so it is always redone when
needed.
