The obvious one is "loader reset function wants to set starting PC to
entry point of kernel/etc" vs "CPU device reset wants to set starting
PC to hardware-mandated reset vector". We have this at the moment, of
course, and I think we implicitly rely on reset handlers being called
in order of registration...

(The other irritating case is where the CPU device reset wants
to read the starting PC out of memory, like the Cortex-M3, but
really that one is because we don't distinguish "going into reset"
from "coming out of reset".)
