driver: systimer: increase esp32c3 tick resolution

Browse source 
hal_espressif systimer HAL calls are based on 1MHz reference.
This changes systimer driver to allow max clocking reference of 16MHz
and increases soc tick resolution by reducing min delay interval.

This also sets all ESP32-C3 socs to 16MHz hardware cycles reference.
