d0d7a7909e driver: uart: esp32: get port number from reg address
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.

9f02eeadf8 serial: allow callback setting to be exclusive
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.

ad1450510a drivers: serial: Refactor drivers to use shared init priority Kconfig
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.

4e1692f85a serial: introduce CONFIG_UART_USE_RUNTIME_CONFIGURE
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.
