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.
