edb32c48a2 smp: Allow switching back to wfe for the smp spinloop 
This is what Linux expects, so we'd better do it in kboot.

c3ba77ce16 hv_exc: Handle SYS_IMP_APL_CYC_OVRD in the fast path 
m1n1 now uses this for SMP, and due to wfi FIQ leakage from the HV
timer this gets spammed thousands of times per second. Handle it in
the HV directly.

Fixes: #107
