Updates to the cpupower command to add support for AMD family 0x19
and cleanup the code to remove many of the family checks to hopefully
make any future family updates easier.

The first couple of patches are simple updates to rename the structs
in the msr_pstate union to better reflect current support and correcting
the name of the CPUPOWER_CAP_AMD_CPB cpuid cap flag.

Patches 3, 5, and 8 update the family checks to either replace
them with a new cpuid cap flag based off of cpuid checks or check for
family >= 0x17 where removing the direct family check isn't possible.

The reamianing patches are cleanups to remove unneeded extra enabled bit
checking, remove passing no longer used variables, and remove unused
variables in decode_pstates().
