Serious regression on NRF52 idle power consumption #7168

@NeilMacMullen

Description

@NeilMacMullen

The current 5.9RC( and head of master) show very poor power consumption when executing

while (1) Thread::wait(5000);

The attached picture shows two traces on the same RF52 based hardware platform. Idle power has increased from ~180uA to 6.4mA suggesting that the processor is not idling at all.
