Adjust the documentation and devicetree overlays so the sample can be
built for any board with an Arduino I2C and SPI pinout, defaulting I2C
and SPI to y to make it easier to switch between the two without
requiring a pristine build.
The user has to choose an appropriate overlay or have a sensor built
in to the board.
Use the newly introduced DEVICE_DT_GET_ANY() in main.c to ask for a
bosch,bme280 without worrying over the details or exposing
DT_DRV_COMPAT-based functionality that is really meant for drivers.
Remove the no-longer-needed board specific overlay for nRF52840 DK;
this is covered by the generic Arduino overlays now.
Fix the datasheet link while we're here.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

I personally don't find it very useful to have to maintain prj.conf
and prj_spi.conf for this sample. The information we need to make
this application "just work" with regards to the bus is available in
the devicetree, and Kconfig can now access it using
dt_compat_on_bus().
Do so, enabling I2C and SPI appropriately when a sensor of the right
type is on either of those buses.
If no sensors are enabled, the user gets the build-time error message
in main.c about no devices being found.
This approach is prone to the "stuck symbol" Kconfig problem covered
in our documentation, so a pristine build is necessary to change the
default settings from a previous build.

Use instance zero of the compatible to get the device instead of
fixing a label. Print the used label for help debugging, and the
results of finding the device (or not), with a hint about what might
have gone wrong in case of failure.

The nrf52840-DK doesn't have this sensor built-in, so it's likely
users will be getting this sensor from a breakout board. The ones that
Sparkfun and Adafruit sell pull up the LSB address pin, so the default
address is 0x77 on those boards.
Let's follow along with them instead of using 0x76, because those are
the boards that come up first in the results when you google "BME280
breakout board" from where I'm sitting.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.
