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.

This patch adds support for using device tree configuration files for
configuring ARM platforms.
In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options. A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.
It should be noted that the host system must provide access to the
device tree compiler (DTC). The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git
This patch also requires the Python yaml package.
