samples: power: power_mgr: Remove redundant test

Browse source 
The removed test does the same thing and runs on the same platforms
as already existing samples/boards/nrf52/power_mgr.

OS Power management demo
###########################
Overview
********
This sample demonstrates OS managed power saving mechanism through the sample
application which will periodically go sleep there by invoking the idle thread
which will call the sys_suspend() to enter into low power states. The Low
Power state will be selected based on the next timeout event.
Requirements
************
This application uses nrf52 DK board for the demo.
Building, Flashing and Running
******************************
.. zephyr-app-commands::
:zephyr-app: samples/subsys/power/power_mgr
:board: nrf52_pca10040
:goals: build flash
:compact:
Running:
1. Open UART terminal.
2. Power Cycle Device.
3. Device will enter into Low Power Modes periodically.
Sample Output

Demo Description
Application creates Idleness, Due to which System Idle Thread is
scheduled and it enters into various Low Power States.
