discover/platform-powerpc: Use IPMI on BMC-based machines only
With a kernel that has IPMI support Petitboot will try to use direct IPMI, however on FSP machines this is not fully functional. Use direct IPMI only on BMC-based machines, and use sysparams otherwise. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
