The current flash configurations for all nRF52840's in Zephyr is
VERY constrained when it comes to allowing samples any space for
storage or custom areas. It only leaves the last 4 pages of flash
for "storage".
The nRF52840 is also capable of using OpenThread which defaults
to using the last 4 pages of flash for storing OpenThread-related
network data.
This means that while using OpenThread under any configuration
designed to use mcuboot partition slots, there is no space left
over for storage of any kind.
Let's adjust the partition table to set storage at 8 pages of
flash (32k). This fixes the conflict with OpenThread and leaves
room for future use cases that may arise.

To build apps for mcuboot, a zephyr,code-partition needs to be
identified in the DTS chosen block. Without this entry, the
following configs will always be 0:
CONFIG_FLASH_LOAD_OFFSET
CONFIG_FLASH_LOAD_SIZE

All Particle mesh devices have an on-board 32 Mibit JEDEC-compatible
flash from GigaDevice. Add bindings to access it.

Provide a dtsi file that sets up common capabilities for all
Feather-based Particle Mesh devices. Provide additional dtsi files for
some obvious peripheral options.
Remove the xtensa esp32 image: it didn't build, and there's no
indication of how the ESP32 firmware can be updated on the Argon board.
Use particle_argon as the nRF52840 side of the board.
Add Particle Boron support.
Note that dtsi files must be replicated in each board directory until
tooling supports DTS includes from a shared area.
