[PATCH] net: xilinx: axi_emac: Fix endless loop when no PHYs are connected

[Michal Simek]

From: Patrick van Gelder <patrick.vangelder at nl.bosch.com>

The index used to iterate over the possible PHYs in axiemac_phy_init was an
unsigned int and decremented. Therefor it was always >= 0 and never exited
the loop.
