With the addition of the timesync driver and looking at the hardware interfaces we have, its clear we need to add a new arche-platform state. This patch adds ARCHE_PLATFORM_STATE_TIME_SYNC to the arche-platform driver to facilitate transition to the TIME_SYNC state if-and-only-if the arche-platform driver is in the ACTIVE state. This is mainly needed as wake/detect lines are shared between TIMESYNC operation and basic control functionality of APBs. So during TIMESYNC we want to make sure that the events on wake/detect lines are ignored by the arche-platform APB reset logic. This patch adds one exported function, which can be invoked from timesync driver code, allowing, switching between ARCHE_PLATFORM_STATE_TIME_SYNC <=> ARCHE_PLATFORM_STATE_ACTIVE states.
