The existing configuration of the ESP32 UART FIFO thresholds

Modbus RTU packages exceeding this size.
This commit introduces two new Kconfig options,

ESP32 uart driver requires uart port number to its low level calls.
In case uart0 is disabled and uart1 is enabled, driver will set
default port num to 0 when it should be 1. This fixes this scenario
by retrieving uart pot number based on periphral address.

- changing the CONFIG_SOC_ESP32* to refer to

- replacing CONFIG_SOC with the CONFIG_SOC_SERIES
- creating CONFIG_SOC_FAMILY_ESP32 to embrace all

- introducing CONFIG_SOC_PART_NUMBER_* to
provide a SOC model config
- introducing the 'common' folder to hide all

Both the IRQ API and Asynchronous API support callback.
However, since they are both interrupt driven, having
callbacks on both API would interfere with each other
in almost all cases. So this adds a kconfig to signal
that the callbacks should be exclusive to each other.
In other words, if one is set, the other should not
be active. Drivers implementing both APIs have been
updated to remove the callbacks from the other API.
Though, this still leaves the option to disable
the kconfig and allows both APIs to have callbacks
if one desires.

HAL call function used to retrieve the configured baudrate
returns the real calculated value, which might not be exactly as
the configured. For baudrate of 115200, HAL api
returns 115201, which then causes uart_basic_api test
to fail. Instead of returning the calculated baudrate value,
returns the configured one.

Refactors all of the serial drivers to use a shared driver class
initialization priority configuration, CONFIG_SERIAL_INIT_PRIORITY, to
allow configuring serial drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The one
exception is uart_lpc11u6x.c which previously used
CONFIG_KERNEL_INIT_PRIORITY_OBJECTS.
This change was motivated by an issue on the frdm_k64f board where the
serial driver was incorrectly initialized before the clock control
driver.

This kconfig option enables runtime configuration of UART
controllers. This allows application to call uart_configure()
to configure the UART controllers and calling uart_config_get()
to retrieve configuration. If this is disabled, UART controllers
rely on UART driver's initialization function to properly
configure the controller. The main use of this option is mainly
code size reduction.
