a73dd07d12 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.

2a6c6c18f7 esp_hw_support: esp_clk should use spinlock instead of mutex
esp_clk used to be protected using _lock_t (i.e., a FreeRTOS Mutex). However, esp_clk API is current called from
from critical sections, thus mutex should not be used (as they can be blocking).

This commit updates esp_clk to use spinlocks for critical sections instead.

60bb5c913d clk_tree: prework of introducing clk subsystem control
1. Clean up clk usage in IDF, replace rtc_clk_xtal/apb_freq_get with
   upper level API esp_clk_xtal/apb_freq
2. Fix small errors and wrong comments related to clock
3. Add clk_tree_defs.h to provide an unified clock id for each chip
   Modify the NGed drivers to adopt new clock ids
