These 2 patches fixed misuse of register for 88e1111.
The problem can be reproduced in my powerpc dev board.
With fiber plugged, start the board in u-boot, the fiber link is
established and data transfer is ok. Booting into kernel with current
marvell.c implementation, and "ifconfig ethX up", the fiber link is lost.
The #1 patch fixed this.
The #2 patch is obvious but I can't test it myself because the board I
have using 88e1111 in GMII mode.
Notice: These two patches didn't fix some auto selection problem yet. I
will discuss the problem in seperate email.
