cortex_m: suggest using hardware srst if VECTRESET used

If the target does not support SYSRESETREQ we fall back to using VECTRESET.
This however does not reset the peripherals and we issue a warning to the user
to suggest using a reset-init script.

Also suggest that using hardware srst will give them the same functionality
as using SYSRESETREQ.
