Refactor action target names Host-start-stop

The target change is:
obmc-chassis-stop -> obmc-host-stop
obmc-chassis-start -> obmc-host-start

Removed CHASSIS_FMT and CHASSIS_LINK_FMT
because they are no longer needed.
CHASSIS_POWER_FMT_2 did not change because
its used for obmc-chassis-reset.

Deleted files obmc-chassis-start@.target and
obmc-chassis-stop@.target because they are
no longer needed. I moved over their contents
to obmc-host-start and obmc-host-stop.

Updated phosphor-state-manager.bb and
skeleton-rev.bbclass to have correct commit
id.
