[POWERPC] don't include powerpc/sysdev/rom.o for arch/ppc builds

[grant.likely at secretlab.ca]

From: Grant Likely <grant.likely at secretlab.ca>

sysdev/rom.c is for arch/powerpc only.  Don't compile it when building
an arch/ppc kernel.

Please include for .20; without this patch you cannot use MTD on an arch/ppc
kernel for the mpc52xx.
