The nRF52840 DK board target, so far known as nrf52840_pca10056,
is renamed to nrf52840dk_nrf52840.
Its documentation and all references to its name in the tree are
updated accordingly. Overlay and configuration files specific to
this board are also renamed, to match the new board name.

Use the new i2c_write_read() wrapper to simplify the code.
Also add several overlays used to test the sensor on a variety of
boards, and conf file support for trigger testing.

This board has headers for these buses so they should be made available
without requiring special overlays.
Also take advantage of the new Nordic auto-enable for peripherals,
which eliminates the need for special configuration.
