This patch enables the GPIO driver by default on all boards equipped
with an nRF SoC (all boards having `CONFIG_SOC_FAMILY_NRF=y` in their
`_defconfig` file).
In vast majority of cases the driver is needed, so it is more
convenient to enable it at board level than in particular
applications.
And if the driver is undesired for some reason, it can be still
disabled in the application config.

The nRF52840-based Particle.io boards have an external flash
module that is connected via SPI interface. Originally,
the goal was to place the flash part into deep power down
mode and save 9 uA in sleep mode, but this was never
implemented in a board initialization file.
Let's remove the default y behavior for SPI as each sample
will turn it on if needed, and it can cause certain out of
tree samples to behave badly (where CONFIG_MULTITHREADING=n).
Long term: we need a better solution for handling samples
that don't fit the requirements for certain drivers, but
for now this will clean up some board usability issues.

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.
