spapr: Add RTAS sysparm SPLPAR Characteristics
Add support for the SPLPAR Characteristics parameter to the emulated
RTAS call ibm,get-system-parameter.
The support provides just enough information to allow "cat
/proc/powerpc/lparcfg" to succeed without generating a kernel error
message.
Without this patch the above command will produce the following kernel
message: arch/powerpc/platforms/pseries/lparcfg.c \
parse_system_parameter_string Error calling get-system-parameter \
(0xfffffffd)
