arch/arm/src/stm32l4/stm32l4_idle.c: (1) Added BEGIN_IDLE()/END_IDLE() to stop call so that we also get notification via LED of the STOP mode, (2) Added the stm32l4_clockenable call as previously discussed, and (3) Added call to pm_changestate() to inform drivers we're back to running after the call to stm32l4_stop() returns.
