net: phy: put genphy_config_init's EXPORT_SYMBOL directly after the function

Commit af6b6967 ("net: phy: export genphy_config_init()") introduced
this EXPORT_SYMBOL and put it after gen10g_soft_reset() instead of
directly after genphy_config_init. Probably this happend when the patch
was applied because http://patchwork.ozlabs.org/patch/339622/

 looks ok.
