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.
