powerpc: Fix kexec-related UP build error

Hello!

The following patch fixes a UP build problem for kexec() on powerpc. When the crash_kexec_wait_realmode() function was added, it was placed in only two of the three required locations.

Thoughts?

Thanx, Paul

------------------------------------------------------------------------

The function crash_kexec_wait_realmode() is defined only if SMP, but is called in UP builds. Create an empty function to keep the compiler happy in UP builds.

Hi Paul,
