x86/suspend: Don't save/restore %cr8

%cr8 is an alias of APIC_TASKPRI, which is handled by
lapic_{suspend,resume}() with the rest of the Local APIC state.  Saving
and restoring the TPR state in isolation is not a clever idea.

Drop it all.

While editing wakeup_prot.S, trim its include list to just the headers
which are used, which is precicely none of them.
