Subject: [PATCH net] Revert "net: phy: fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register"

This reverts commit b45396afa4177f2b1ddfeff7185da733fade1dc3 ("net: phy:
fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register")
since it prevents any system that uses a fixed PHY without a GPIO
descriptor from properly working:

[    5.971952] brcm-systemport 9300000.ethernet: failed to register fixed PHY
[    5.978854] brcm-systemport: probe of 9300000.ethernet failed with error -22
[    5.986047] brcm-systemport 9400000.ethernet: failed to register fixed PHY
[    5.992947] brcm-systemport: probe of 9400000.ethernet failed with error -22

Fixes: b45396afa417 ("net: phy: fixed_phy: Fix NULL vs IS_ERR() checking in __fixed_phy_register")
