Subject: [PATCH v2 4/4] net: emac: add deprecation notice to emac custom phy users

From: Christian Lamparter <chunkeey@...glemail.com>

This patch starts the deprecation process of emac's small library of
supported phys by adding a message to inform all remaining users to
start looking into converting their platform's device-tree to PHYLIB.

EMAC's phy.c support is limited to mostly single ethernet transceivers:
CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035.

And Linux has dedicated PHYLIB drivers for all but the BCM5248 which
can be supported by the generic phy driver.
