Use the clock control interface instead of calling CLOCK_GetFreq()
directly. This will allow SoCs with different clock architectures to
reuse this driver.

As not all drivers support interrupts we don't have a means to know if
we can allow UART_INTERRUPT_DRIVEN to be enabled and thus various
Kconfig options that select UART_INTERRUPT_DRIVEN. Some drivers have a
interrupts, however not all do. So introduce a Kconfig option to let us
know what the driver actually supports.

Now that we can utilize label in the device tree we can convert to
getting the device name for the NXP Kinetis UART out of the device tree
instead of from Kconfig.

Now that all NXP MCUX platforms are using device tree we can remove the
handling for !HAS_DTS from the serial drivers.

This patch adds DTS support and related files for the NXP Kinetis
platform. The DTS files contain the base definitions for the hardware
nodes on Kinetis platforms. The YAML files provide the definitions of
the contents of the DTS nodes.
The Kconfig changes were put in place to allow for the conversion of
existing drivers. Once those drivers are modified, the Kconfig options
that are replaced by the DTS information will be removed.

The NXP copyright should not have 'Semiconductors, Inc' in it.

Adds a shim layer around the mcux uart driver to adapt it to the Zephyr
serial interface. Unlike the existing (and confusingly-named) uart_k20
driver, this driver can be used for k64 and other Kinetis SoCs.
Implements polling and interrupt-driven serial interface functions that
are logically equivalent to the uart_k20 driver. Adds an extra instance,
irq_tx_empty(), and err_check() that aren't implemented in the uart_k20
driver.
