tools/power/x86/intel-speed-select: Implement CascadeLake-N help and command function...

CascadeLake-N only supports SST-BF and needs some of the perf-profile
commands, and the base-freq commands.

Add help functions, and create an empty command structures (the functions
will be implemented later in this patchset).  Call these functions
when running on CascadeLake-N.
