[PATCH] powerpc: restore eeh_add_device_late() prototype

[Mark Fasheh <mark.fasheh@oracle.com>]

A search on the linux-kernel, linuxppc-dev mailing lists and the git tree at
 git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc didn't show
this issue fixed or reported. If I missed something please ignore :)

I get a compile failure trying to build a powerpc kernel:

arch/powerpc/platforms/pseries/eeh.c: In function `eeh_add_device_tree_late':
arch/powerpc/platforms/pseries/eeh.c:901: warning: implicit declaration of function `eeh_add_device_late'
arch/powerpc/platforms/pseries/eeh.c: At top level:
arch/powerpc/platforms/pseries/eeh.c:918: error: conflicting types for 'eeh_add_device_late'
arch/powerpc/platforms/pseries/eeh.c:901: error: previous implicit declaration of 'eeh_add_device_late' was here
make[2]: *** [arch/powerpc/platforms/pseries/eeh.o] Error 1

It seems commit 827c1a6c1a5dcb2902fecfb648f9af6a532934eb removed this
prototype from eeh.h. The following patch restores it.
