When APB clock frequency changes, high-resolution timer (esp_timer)

small error, and over time such small errors may cause time drift.

When APB clock frequency changes, high-resolution timer (esp_timer)

scale and base value need to be adjusted. Each adjustment may cause

small error, and over time such small errors may cause time drift.
