ARM: dts: renesas: Add compatible properties to LAN8710A Ethernet PHYs

Browse Source 
Add compatible values to Ethernet PHY subnodes representing SMSC
LAN8710A PHYs on RZ/A1 and R-Mobile A1 boards.  This allows software to
identify the PHY model at any time, regardless of the state of the PHY
reset line.

Ported from Linux kernel commit 1c65ef1c71e473c00f2a7a1b9c140f0b4862f282 .
