generate bmc dump if hw indicates host running

This situation has been hit a few times and it has been requested a BMC
dump be generated when the condition is hit. This dump will help debug
why the BMC is unable to communicate with the host.

Tested:
- Caused the error path and verified a BMC dump was requested

bmc-reset: add support to clear host running register

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

bmc-reset: check if host is running

This is the backup plan to ensuring the host is not running before the
BMC issues a power off to the system. Prior to this procedure being
called, the BMC has tried all other communication mechanisms to talk
with the host and they have failed. The design is that the host
firmware will write the value 0xA5000001 to Mailbox scratch register
12 when they are up and running to a point where communication to the
BMC is no longer required to function. On a power off or shutdown
this register is cleared by the host and BMC firmware. If the BMC sees
the 0xA5000001 pattern in the scratch register then it assumes the host
is running and will leave power on to the system.

Why not put this in phosphor-state-manager where the other checks are
for the host running?
- This is a very POWER10 specific piece of logic
- A lot of tight coupling would have been required between state-manager
and proc-control
- In the end, it was less work to just put this in proc-control

Tested:
- Verified when CFAM is not A5000001, call returns without error and
/run file is not created
- Verified when CFAM is A5000001, call returns without error and /run
file is created
