This patch extends samples/power/quark_se application so it supports 'sleep' and 'deep sleep' power states. According to spec, in these states, the core voltage rail is turned off. In order to be able to continue the program execution from the point it was before entering in Sleep states, we have to save the execution context and restore it during system startup. The current version of QMSI doesn't provide that feature so we implement it in the sample application. In future, QMSI will provide this functionality and we will remove it from application code. Even though the _sys_soc_resume hook could be easily implemented in C, it was implemented in assembly. During Zephyr initialization, _sys_soc_ resume hook is called before the C-runtime is initialized so implementing this function in C doesn't look appropriate. It may pass the wrong idea that we have the C-runtime properly initialized, which is not true.
