Subject: [PATCH v3 3/3 net-next] net: phy: add constant for "Clause 22
 registers present" flags in device list bitmap

Bit 0 ("Clause 22 registers present") is a flag and doesn't represent
a device, therefore don't define a MDIO_MMD_XYZ constant, just define
a MDIO_DEVS_XYZ constant for the flag in the device list bitmap.
