Remove prompts from Kconfig options `UART_x_NRF_UART*` that select
the type of nrfx driver (for UART or UARTE peripheral) to be used
for a given instance. This prevents the options from being modified
from configuration files.
Instead, make one of these options selected by default according to the
"compatible" property set for the corresponding UART node in devicetree.
This eliminates the need of changing both the "compatible" property in
devicetree and the Kconfig option selecting the driver type when a user
wants to switch between UART and UARTE for a given instance.
Since all `UART_x_NRF_UART*` options are made "hidden" by this commit,
all their occurrences in configuration files are removed.

We rename the nRF91 Dev Kit board target (nrf9160_pca10090)
to nrf9160dk_nrf9160. We update all associated references
in the supportive documentation and all nRF9160-related
cofigurations and overlay files in the samples and tests
in the tree.

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.

Application board.overlay files tend to be paired with
boards/board.conf files that extend the functionality of a board.
Move the overlay files to the same location as the config files that
they work with.
A few overlay files that are paired with a prj_board.conf file in the
application root directory are left in place.

Added tests for async UART API and test configuration for
nrf52840_pca10056 board.
For tests to work, RX and TX pins have to be connected together
and second UART is needed to output results to console.
