Previous code was piggy backing the memory preserving reboot function
off of the phal machine feature. This had issues in that a
witherspoon-tacoma system also supports mpreboot, but does not support
phal.

For phal based systems, move the memory preserving reboot function to
the obmc-host-crash target. This target is currently un-used on phal
based systems.
Make this move so that the obmc-host-diagnostic target can be utilized
as a more generic target. Dumps like hostboot, sbe, and hardware can now
utilize the obmc-host-diagnostic target to ensure the user knows when
any type of diagnostic event is occurring in the system.
Note that the obmc-host-diagnostic target will still be started as a
part of obmc-host-crash since that target is what communicates to
outside users that a diagnostic action is occurring.
To ensure we do not regress the dump functionality on our non-pHAL
systems, ensure the obmc-host-quiesce target remains within the
obmc-host-crash target. Our non pHAL systems go straight to quiesce on a
crash target call.
Tested:
- Verified with all commits in this Topic that the witherspoon system
has the same service layout as before and the rainier system
has the new layout (crash used for mpipl)

When the obmc-host-quiesce@.target was initially created the idea was to
leave the system in the state it was in. In most cases the host had
crashed.
As OpenBMC has grown, the use cases for the quiesce target have grown.
For example the Quiesce On Hardware Error design:
https://github.com/openbmc/docs/blob/master/designs/fail-boot-on-hw-error.md
When the QuiesceOnHwError setting is enabled, the host will be put in a
Quiesce state to indicate that an error has occurred. In a lot of cases
though the host actually can (and does) continue to boot. This causes a
lot of confusion for the user (host state shows Quiesce but host is
still booting).
This commit adds the op-stop-instructions.service to the quiesce target
to ensure the host is actually stopped when quiesce is entered.
Tested:
- Disabled AutoReboot and turned on QuiesceOnHwError. Verified when an
error which triggers QuiesceOnHwError was injected, the host state went
to Quiesce and the host was stopped via the stop instructions.

Changes:
-Adding support for new service
i.e. proc-pre-poweroff@.service, which will be called
during poweroff.

The POWER CEC system device tree need reinitialize before doing
normal ipl to mark required targets as functional for ipling.
The service file is added in below patch.

The corresponding change in openpower-proc-control has more details:
https://gerrit.openbmc-project.xyz/c/openbmc/openpower-proc-control/+/31265
The summary is that the cfam-reset is being removed from the power
control application and into its own service. This ensure it is run when
it is needed (i.e. warm reboots) and that future systems which may use
different power control or have different cfam reset requirements can
easily configure the function.
Tested:
- Verified chassison behaved as expected on witherspoon
- Verified normal power on/off works as expected on witherspoon
- Verified warm reboot works as expected on witherspoon
- Verified bmc reset with host up still works as expected

There have been some situations where things get so messed up that you
can not even stop the instructions on your processor. When this happens,
the systemd target, obmc-host-stop can not complete. This really should
be a wants relationship vs. a requires so that the target can continue
to stop the host even when this service fails.

The cfam_override@.service is required in two situations:
- When chassis power is turned on (to ensure proper workarounds
and overrides are in place)
- When the host is warm rebooted (i.e. no chassis power is turned
off/on)
Install this service in both targets and ensure it only runs once per
boot.
Tested:
- Verified service was only run once during a cold boot
- Verified overrides were correctly applied on a warm reboot
