During controller transitioning to READY state, if the controller is found
in transient states ("becoming ready" or "reset requested"), driver waits
for 510 secs even if the controller transitions out of these states
early. This causes an unnecessary delay of 510 secs in the overall firmware
initialization sequence.
Poll the controller state periodically (every 100 milliseconds) while
waiting for the controller to come out of the mentioned transient
states. Once the controller transits out of the transient states, come out
of the wait loop.
