baa28b54a2 esp_hw_support: Fix esp_light_sleep_start() deadlock 
esp_light_sleep_start() will stall the other CPU via esp_ipc_isr_stall_other_cpu(). After stalling the other CPU,
will call esp_clk_... API which themselves take locks. If the other stalled CPU is holding those locks, this will
result in a deadlock.

This commit adds a workaround calling esp_clk_private_lock() to take the lock before stalling the other CPU.

90c63f7250 esp_system: ipc_isr does not use its own initialization task, it is done from ipc_task() 
It helps to reduce the memory usage at startup.
