Register a resume pmf(9) handler that clears the status. It is needed 

to always fetch new status after resuming, otherwise if AACAD_F_AVAILABLE
is set, acpiacad_get_status() won't be called.

Also use the SME_INIT_REFRESH flag to fetch sensor data once in the
autoconf(9) process.

Ok'ed by <jmcneill>.
