ibm_newemac: Fix section mismatch warnings

This patch fixes several section mismatch warnings in the
ibm_newemac driver similar to:

WARNING: vmlinux.o(.devinit.text+0x3a04): Section mismatch in reference from the function emac_probe() to the function .devexit.text:tah_detach()
The function __devinit emac_probe() references
a function __devexit tah_detach().
