cpupower: Remove mc and smt power aware scheduler info/settings

These kernel interfaces got removed by:

commit 8e7fbcbc22c12414bcc9dfdd683637f58fb32759
Author: Peter Zijlstra <peterz@infradead.org>

    sched: Remove stale power aware scheduling remnants and dysfunctional knobs

No need to further keep them as userspace configurations.

-\-\-sched\-mc utilizes cores in one processor package/socket first before
-processes are scheduled to other processor packages/sockets.
-
-\-\-sched\-smt utilizes thread siblings of one processor core first before
-processes are scheduled to other cores.
-
-The impact on power consumption and performance (positiv or negativ) heavily
-depends on processor support for deep sleep states, frequency scaling and
-frequency boost modes and their dependencies between other thread siblings
-and processor cores.
-
-Taken over from kernel documentation:
-
-Adjust the kernel's multi-core scheduler support.
-
-Possible values are:
-.RS 2
-0 - No power saving load balance (default value)
-
-1 - Fill one thread/core/package first for long running threads
-
-2 - Also bias task wakeups to semi-idle cpu package for power
-savings
