Provided nodes reflect the clock tree of each series.
Clock nodes are disabled by default but populated with default
start up configuration. Main reason is the we don't want to
impact boards using Kconfig based clock configuration for now.
Exception to these rules:
- syslck: Default enabled, clock frequency and clock source not
provided
- pll: clock source not provided
This is made on purpose so that errors are triggered if parameters
essential to the board configuration are not provided.

Since there are times that we include a base .dtsi file and change the
reg address we tend to end up with warnings that the reg address and
unit-address don't match. To handle this introduce a simple DT_ADDR(x)
macro that will prepend '0x' to a 'unit-address' style address.
#define DCCM_ADDR 80000000 /* in unit-address format */
dccm0: dccm@DCCM_ADDR {
reg = <DT_ADDR(DCCM_ADDR) 0x1>;
...
};
This allows the dts file to override the value of DCCM_ADDR and than to
have the unit-address of the node and the reg address match.

Remove the common.dts file which has been used for a year.
common.dts at one point allowed us to conditionally add an MCUBoot
overlay based on Kconfig.
but since DT lost access to Kconfig options it has been unused.
The overridable variable DTS_COMMON_OVERLAYS, which by default points
to common.dts, is also unused in-tree, and any out-of-tree usage can
be ported over to use DTC_OVERLAY_FILE instead, so we remove the
variable as well.
This simplifies the configuration system.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

As we want to remove dts dependency on Kconfig, we had a case based on
CONFIG_BOOTLOADER_MCUBOOT. From a DTS point of view that was just
getting the chosen property 'zephyr,code-partition' set. We can easily
move this to the actual dts files and remove the mcuboot.overlay.

To move forward and remove use of Kconfig in dts files lets just create
SoC specific dtsi files that the boards can include. This lets us
remove:
CONFIG_SOC_CC3220SF
CONFIG_SOC_MSP432P401R

When the Kconfig BOOTLOADER_MCUBOOT is selected, an overlay to place the
image at the slot0 location is required. In order to avoid having to do
this manually for all samples when targetting MCUboot, include the logic
inside the dts.cmake script to prepend a new common.dts file that then
conditionally includes mcuboot.overlay.

Added flash-controller description and moved flash description to

Thanks to that l-value FLASH_WRITE_BLOCK_SIZE macro

Devicetree.org specifies that serial devices property used to set
baud rate is "current-speed", while zephyr uses "baud-rate".
Align property name in order to keep zephyr dts files compatible
with device tree specification and could be re-used from/to
Linux for instance. We also cleanup a few SoCs that set "baud-rate" in
the SoC dts and not the board.

This patch adds the base DTS and YAML files that may be referenced by
SoCs. The device tree files provide base definitions for the more well
known ARMV7M device nodes. These files are meant to be included in
SoC vendor specific device tree files.
The YAML files provide definitions for the contents of device tree node
that contain information that will be parsed and used for configuration
in the system.
DTS files define hardware and software configuration and YAML files
provide the markers for knowing which pieces need to be extracted.
