[PATCH] arm: dts: am335x-bone-common: add collision and carrier sense pinmux

From: Schuyler Patton <redacted> Added pin mux definitions for collision and carrier sense errors coming from the ethernet phy. Without these two signals the MAC ends up ignoring the errors detected by the PHY which end up causing a lower throughput problem when the phy is in half duplex mode such as connected through a hub.
