ucc_geth: Fix the wrong the Rx/Tx FIFO size
current the Rx/Tx FIFO size settings cause problem
when four UEC ethernets work simultaneously.
eg: GETH1, UEM-J15, GETH2, UEC-J5 on 8569MDS board
$ ifconfig eth0 10.193.20.166
$ ifconfig eth1 10.193.20.167
$ ifconfig eth2 10.193.20.168
then
$ ifconfig eth3 10.193.20.169
The fourth ethernet will cause all of interface broken,
you cann't ping successfully any more.
The patch fix this issue for MPC8569 Rev1.0 and Rev2.0
