Corey Minyard d941aeae42 ipmi: add new kernel options to prevent automatic ipmi init
The configuration change building ipmi_si into the kernel precludes the
use of a custom driver that can utilize more than one KCS interface,
multiple IPMBs, and more than one BMC.  This capability is important for
fault-tolerant systems.

Even if the kernel option ipmi_si.trydefaults=0 is specified, ipmi_si
discovers and claims one of the KCS interfaces on a Stratus server.  The
inability to now prevent the kernel from managing this device is a
regression from previous kernels.  The regression breaks a capability
fault-tolerant vendors have relied upon.

To support both ACPI opregion access and the need to avoid activation of
ipmi_si on some platforms, we've added two new kernel options,
ipmi_si.tryacpi and ipmi_si.trydmi be added to prevent ipmi_si from
initializing when these options are set to 0 on the kernel command line.
With these options at the default value of 1, ipmi_si init proceeds
according to the kernel default.
