[PATCH] ipmi: add hacks for IPMI chassis poweroff for certain Dell servers

This patch allows Dell servers with IPMI controllers that predate IPMI 1.5
to use the standard poweroff or powercycle commands.  These systems
firmware don't set the chassis capability bit in the Get Device ID, but
they do implement the standard poweroff and powercycle commands.

Tested on RHEL3 kernel 2.4.21-20.ELsmp on a PowerEdge 2600.  The standard
ipmi_poweroff driver cannot drive these systems.  With this patch, they
power off or powercycle as expected.
