[PATCH v2 2/2] net: mdio: fixup ethernet phy module auto-load function

[Yinbo Zhu <zhuyinbo@loongson.cn>]

the phy_id is only phy identifier, that phy module auto-load function
should according the phy_id event rather than other information, this
patch is remove other unnecessary information and add phy_id event in
mdio_uevent function and ethernet phy module auto-load function will
work well.
