[U-Boot] [PATCH] da850: fix the channel number for EMAC teardown init

From: Nagabhushana Netagunte <nagabhushana.netagunte@ti.com>

TX and RX channel numbers programmed as '1' during EMAC teardown initialization
is wrong. This patch fixes the same by setting channel number to '0' which is
used by U-boot.
