Subject: [PATCH v2 2/2] ARM: dts: Add the ethernet and ethernet PHY to the cygnus core DT.

Cygnus has a single AMAC controller connected to the B53 switch with 2
PHYs.  On the BCM911360_EP platform, those two PHYs are connected to
the external ethernet jacks.

Signed-off-by: Eric Anholt <eric@...olt.net>
Reviewed-by: Florian Fainelli <f.fainelli@...il.com>
---

v2: Call the node "switch", just call the ports "port" (suggestions by
    Florian), drop max-speed on the phys (suggestion by Andrew Lunn),
    call the other nodes "ethernet" and "ethernet-phy" (suggestions by
    Sergei Shtylyov)
