bmc-reset: add support to clear host running register

A simple procedure to ensure the CFAM register used by the host to
communicate when it is up and running, is cleared when the host is
stopped.

The host is also responsible for clearing this but given there are
scenarios where the host crashes, this is the backup plan to ensure it
is cleared.

Its a best effort because there's not much to be done if it cannot be
cleared. We want the default to lean towards not powering down the host
if there is any chance the host is running.

Tested:
- Verified master processor CFAM register was set to 0 when this
  procedure was called
