607464f8b0 proxy/uartproxy/hv_asm: Add syncs to flush SErrors 
This makes sure any pending memory ops that might trigger an
asynchronous SError do so here, and not later. This fixes SErrors
breaking proxy ops.

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.
