[PATCH] ia64: platform_kernel_launch_event is noop on generic kernel

Add a missing #define for the platform_kernel_launch_event.  Without this
fix, a call to platform_kernel_launch_event() becomes a noop on generic
kernels.  SN systems require this fix to successfully kdump/kexec from
certain hardware errors.
