ESP32 - S2,S3 and C3 variants have only 14 bits counter.
where as the plain ESP32 variant has 20 bits counter.
application failed to set low frequency(1Hz) in S2, S3 and C3 variants.
to get very low frequencies on these variants,
frequency needs to be tuned with 18 bits clock divider.
so select the slow clock source (1MHz) with highest counter resolution.
this can be handled on the func'pwm_led_esp32_timer_set' with 'prescaler'.

This PR updates GPIO driver to use DTS information
regarding gpio availability.
This also fixes interrupt handling and
also removes kconfig definition for GPIO port.
A few configuration checks were also added to
improve code usage.

Disable RTC WDT enabled (by default) by 2nd stage bootloader in ESP-IDF.
This WDT timer ensures correct hand-over and startup sequence from
bootloader to application.
Enabling bootloader caused system clock initialization to fail
when clock rate is greater then 80MHz. This also fixes
esp32 clock source code.

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.

- Updates gpio driver and device tree files to the new GPIO Config flags
- Implements the new port_* APIs
- Update I2C and PWM Drivers to use new GPIO config
- Add esp32.overlay to gpio_basic_api test
- refactor convert_int_type, regs struct
- remove config_polarity
- add kConfig notes
Tests:
- samples/basic/blinky
- samples/basic/button
- tests/drivers/gpio/gpio_basic_api
- tests/drivers/gpio/gpio_api_1pin
Board:
- esp32 DevKitC V4
Note about interrupts:
The ESP32 requires specifying a CPU interrupt to be used for GPIO
interrupt signals. CPU interrupts can be either level or edge (or
special) triggered, but not both.
Please check gpio/Kconfig.esp32 for more info.

Add support for requesting an inverted PWM pulse (active-low) when
setting up the period and pulse width of a PWM pin. This is useful
when driving external, active-low circuitry (e.g. an LED) with a PWM
signal.
All in-tree PWM drivers is updated to match the new API signature, but
no driver support for inverted PWM signals is added yet.
All in-tree PWM consumers are updated to pass a flags value of 0
(0 meaning default, which is normal PWM polarity).
Fixes#21384.
