Address wake from sleep instability (#11450)
* resolve race condition between suspend and wake in LUFA
* avoid multiple calls to suspend_power_down() / suspend_wakeup_init()
* Remove duplicate suspend_power_down_kb() call
* pause on wakeup to wait for USB state to settle
* need the repeated suspend_power_down() (that's where the sleep is)
* more efficient implementation
* fine tune the pause after sending wakeup
* speculative chibios version of pause-after-wake
* make wakeup delay configurable, and adjust value
* better location for wakeup delay
