ESP32C6 Timers: Only Timer(0) and Timer(2) are functional for ESP32-C6 v1.24 #16438

Description

Port, board and/or hardware

esp32-c6, generic board

MicroPython version

Micropython 1.24 custom compile only adding graphics library that does not use timer

Reproduction

not (likely) a build issue (I did not test on stock release firmware)

Expected behaviour

examples from Micropython documentation on Timer class:

WORKS CORRECTLY:
from machine import Timer
tim0 = Timer(0)
tim0.init(period=5000, mode=Timer.ONE_SHOT, callback=lambda t:print(0))

FAILS:
from machine import Timer
tim1 = Timer(1)
tim1.init(period=2000, mode=Timer.ONE_SHOT, callback=lambda t:print(1))

WORKS CORRECTLY:
from machine import Timer
tim2 = Timer(2)
tim2.init(period=5000, mode=Timer.ONE_SHOT, callback=lambda t:print(2))

FAILS:
from machine import Timer
tim3 = Timer(3)
tim3.init(period=2000, mode=Timer.ONE_SHOT, callback=lambda t:print(3))

Observed behaviour

code for Timer0 returns a '0'
code for Timer1 returns nothing
code for Timer2 returns a '2'
code for Timer3 returns nothing

Additional Information

The fix is to make the timer code for the ESP32-C6 behave like the ESP32-C3:

it appears the fix should be in the esp32 port file machine_timer.c line 79 which should be changed from:
#if CONFIG_IDF_TARGET_ESP32C3
to
#if CONFIG_IDF_TARGET_ESP32C3 or CONFIG_IDF_TARGET_ESP32C6 (or something like that because I do not know the syntax)
