Subject: [PATCH 3.19 062/177] ARM: at91/dt: sama5d3 xplained: add phy address for macb1

3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicolas Ferre <nicolas.ferre@...el.com>

commit 98b80987c940956da48f0c703f60340128bb8521 upstream.

After 57a38effa598 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
the macb1 interface refuses to work properly because it tries
to cling to address 0 which isn't able to communicate in broadcast with
the mac anymore. The micrel phy on the board is actually configured
to show up at address 1.
Adding the phy node and its real address fixes the issue.
