* Fix analogWrite channel available verification
The last channel allocated is number 0, which conflicted with the value given to an uninitialized pin, giving the "No more analogWrite channels available!" error when trying to use it
Pins are now given the value -1 to indicate that they are not used so channel 0 can be used without errors.
* Fix incorrect array initialization
Keeping array of zeros for `pin_to_channel` and shifting stored channel
values by +1 to keep the pin with channel 0 from being interpreted as unused.

* Get channel assigned to the pin with analogWrite
* Respect coding standard in LEDC source file

* GPIO refactoring
GPIO now using ESP-IDF API on all chips.
LEDC interrupt fix removed - no longer needed.
Edited pins_arduino.h in variants according to changes in gpio.
* Edited analog channels functions
This PR is refactoring of LEDC HAL in order to use IDF instead of current Register manipulation approach.
Fixing duty -> if all bits in resolution are set -> FULL ON
This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

* `ledcWriteTone()` added a `apbcallback()` evertime the tone value was non zero.
* `addApbChangeCallback()` did not detect duplicate callbacks.
* changed the apbcallback list to a double link to support roll forward, roll back execution. This made the sequences of clock change callback start with the newest registered -> to oldest on the `before` then oldest -> newest after the clock change. This made the UART debug log output have minimal gibberish during the clock change.
* change how the UART callback handled the MUTEX because if any `apbchangeCallback()` executed a `log_x()` a deadlock would occur.
This fixes#3555
* Add APB change callbacks and move cpu code to own file
* Properly set esp_timer and FreeRTOS tick dividers
* Improve updated devisors
* No need to update REF_TICK yet
* Add initial handling for UART baud change
* fix uartWriteBuf and uartDetectBaudrate
* trigger callbacks even when APB did not change
* toggle UART ISR on CPU change
* add XTAL freq getter and add cpu freq validation
* Support CPU frequency changes in I2C (#2287)
**esp32-hal-i2c.c**
* add callback for cpu frequency changes
* adjust fifo thresholds based on cpu frequency and i2c bus frequency
* reduce i2c bus frequency if differential is too small
**Wire.h**
* version to 1.1.0
* Implement clock change for the other peripherals
* remove bad CPU clock values from the menu
* Add note to CPU freqs that support WiFi and BT
* Add support to HAL for APB frequencies different than 80MHz
* Add support for CPU frequencies in the IDE board menu
* Switch to fast set_config
* Add method to uart so debug can be reassigned after apb frequency switch
* Return real APB frequency
* Update mDNS and LEDC
* update toolchain
* Update IDF to 1c3dd23
* Advertise the board variant for Arduino OTA
* Add generic variant definition for mDNS
IDF Options:
- Autostart Arduino (implements app_main)
- Disable HAL locks
- Set HAL debug level
- Auto-connect STA if configured (else will connect after WiFi.begin())
