boot state: run timers on state entry
When TIMER_QUEUE is configured on call the timer callbacks on entry into a state but before its entry callbacks. In addition provide a barrier to the following states so that timers are drained before proceeding. This allows for blocking state traversal for key components of boot. BS_OS_RESUME BS_WRITE_TABLES BS_PAYLOAD_LOAD BS_PAYLOAD_BOOT Future functionality consists of evaluating the timer callbacks within the device tree. One example is dev_initialize() as that seems state seems to take 90% of the boot time. The timer callbacks could then be ran in a more granular manner.
