x86, mrst: Conditionally register cpu hotplug notifier for apbt
APB timer is used on Moorestown platforms but not on a standard PC.
If APB timer code is compiled in but not initialized at run-time due
to lack of FW reported SFI table, kernel would panic when the non-boot
CPUs are offlined and notifier is called.

This patch ensures CPU hotplug notifier for APB timer is only registered
when the APBT timer block is initialized.
