fix(esp_timer): enable systimer functional clock on ESP32-S31

Browse Source 
ESP32-S31 has a separate functional clock gate for the systimer
(reg_systimer_clk_en in HP_SYS_CLKRST) that defaults to off. Without
it, the counter snapshot never completes, hanging execution inside
esp_timer_init_nonos.
