Subject: powerpc: fix system.h fallout in sysdev/scom.c [chroma_defconfig]

The following shows up in chroma_defconfig:

 CC      arch/powerpc/sysdev/scom.o
arch/powerpc/sysdev/scom.c: In function 'scom_debug_init':
arch/powerpc/sysdev/scom.c:182:36: error: 'powerpc_debugfs_root' undeclared (first use in this function)
arch/powerpc/sysdev/scom.c:182:36: note: each undeclared identifier is reported only once for each function it appears in
make[2]: *** [arch/powerpc/sysdev/scom.o] Error 1
make[1]: *** [arch/powerpc/sysdev/scom.o] Error 2

A bisect leads to commit 9ffc93f203c18a70623f21950f1dd473c9ec48cd

    "Remove all #inclusions of asm/system.h"

Add the debug header which contains powerpc_debugfs_root.
