Ivan Grokhotkov	8c307a5720	sleep: fix deadlock in esp_timer_impl_advance after light sleep ... When light sleep is started, the other CPU gets halted using DPORT stall mechanism. This can happen while it is inside an esp_timer critical section, which may lead to a deadlock. This change adds functions to take and release esp_timer lock before entering DPORT critical section, preventing the deadlock.	2018-05-09 22:52:50 +08:00
