powerpc/pseries: Export data from new hcall H_EM_GET_PARMS
Add support for H_EM_GET_PARMS hcall that will return data
related to power modes from the platform. Export the data
directly to user space for administrative tools to interpret
and use.
cat /proc/powerpc/lparcfg will export power mode data
