/**
* @brief ROM patch for systimer HAL
*
* Some chips have systimer HAL implementations in ROM that require patches.
* This file provides the necessary patches when ROM implementation is used.
*
* For chips with ESP_ROM_SYSTIMER_INIT_PATCH defined (e.g., ESP32-C5, ESP32-C6,
* ESP32-H2, ESP32-P4), the ROM systimer_hal_init/deinit functions do not
* enable ETM, so we need to patch them here.
