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 ARM CMSDK APB UART out of the device
tree instead of from Kconfig.

As we now only support DTS for ARM based SoCs we can remove any
associated !HAS_DTS bits in Kconfig. The Nordic NRF5 serial driver and
the ARM CMSDK APB serial drivers had Kconfig bits related to !HAS_DTS
builds.

This patch adds DTS support to the ARM CMSDK UART driver. The DTS
currently specifies the IRQ, IRQ PRIO, and base address of the port.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Add driver for CMSDK APB UART ports. The driver implements RX and TX
functionalities. Data transmission is implemented using polling and
interrupts. The driver default configuration for the port is to use
8bit data transmission, 1 stop bit, no parity control.
The driver exposes a public uart driver API and allows to register up
to five UART devices: from 'UART_0' to 'UART_4'. The driver performs
the required pinmux, the clock control configuration is left to the
platform.
The driver has been verified to work with the Hello World sample
application on a Beetle Board.
