We assumed that ${BOARD} and ${BOARD_FAMILY} are always the same and
thus interchangeable. That isn't always the case so use ${BOARD} proper
for when we mean the exact BOARD name we are building for vs the
BOARD_FAMILY.
We also add .dts files for board variants within a board family, such
that we have a .dts matching each board name.

Per arch the path to the SOC dir that we would find dts.fixup varies
between being ${CONFIG_SOC_FAMILY}/${CONFIG_SOC_SERIES} and just
${CONFIG_SOC}. The ${SOC_PATH} var handles defining this correct so
use it instead when we define DTS_SOC_FIXUP_FILE.

This is one way we can support out of tree board definitions. Basically
all this needs is a board definition in the application source directory
that follows the same structure we have in the main Zephyr tree (also
allowing multiple custom boards). An application tree would look like
this for example:
boards/
CMakeLists.txt
prj.conf
README.rst
src/
with boards following the same structure as in Zephyr:
.
├── boards
│ └── x86
│ └── arduino_101
│ ├── doc
│ │ └── img
│ └── support
└── src
To use this, you need to specify the BOARD_ROOT variable on the command
line when building:
cmake -DBOARD=<board name> -DBOARD_ROOT=<path to boards> ..

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.
