ucc_geth: Fix netdev watchdog triggering on suspend
Sometimes ucc_geth fails to suspend with the following trace:
ucc_geth e0103000.ucc: suspend
ucc_geth e0102000.ucc: suspend
NETDEV WATCHDOG: eth0 (ucc_geth): transmit queue 0 timed out

This patch fixes the issue by properly detaching the device on
suspend, and attaching it back on resume.
