Subject: powerpc: Correct dependency of KEXEC

commit 28794d34ecb6815a3fa0a4256027c9b081a17c5f ("powerpc/kconfig: Kill
PPC_MULTIPLATFORM") broke KEXEC, by making it dependant on BOOK3S, while it
should be PPC_BOOK3S.

 	  kexec is a system call that implements the ability to shutdown your
 	  current kernel, and to start another kernel.  It is like a reboot
