Revert "Allow ADB on boot."

This reverts commit 8e296138df6813083f4adcccc5660429ef6f62ce.

Didnt work, ADB was not enabled on boot. only after MTP access.
Default HOTPLUG helper tuning.

*When ROM MP activated it's set run_queue_poll_ms = 10
and that make cpu 0 to jump to max freq too much. when 20 it's idle
as expected.
*When ROM MP activated it's set running CPU GOV sampling_rate to 10000!
well that is not what i want, fix this too.
*Allow to mode sampling_rate on wake/sleep even if cortexbrain_cpu in not ON.
it's critical battery saver. or performance booster. need to control it.
