/**
 * When compiling G0-layer only, we can't depend on `esp_hw_support` component.
 * However, `esp_private/regi2c_ctrl.h` is part of that component.
 * Thus, if we don't have this header file in our compilation unit, we should use
 * ROM functions.
 * The main difference is that `regi2c_ctrl.h` implementation protects the functions
 * with mutex. ROM functions must be protected explicitly by the user.
