ipmi/parisc: Add IPMI chassis poweroff for certain HP PA-RISC and IA-64 servers
This patch allows HP PA-RISC servers like rp3410/rp3440 and the HP C8000 workstation with an IPMI controller 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.
