Fabio Baltieri 7db1d17ee3 yamllint: fix all yamllint line-length errors 
Fix all line-length errors detected by yamllint:

yamllint -f parsable -c .yamllint $( find -regex '.*\.y[a]*ml' ) | \
  grep '(line-length)'

Using a limit is set to 100 columns, not touching the commandlines in
GitHub workflows (at least for now).

NVS: Non-Volatile Storage
#########################

Overview
********

This is a simple application demonstrating use of the NVS
module for non-volatile (flash) storage.  In this application,
a counter is incremented on every reboot and stored in flash,
the application reboots, and the reboot counter data is retrieved.

Requirements
************

* A board with flash support

Building and Running
********************

This sample can be found under :zephyr_file:`samples/subsys/nvs` in the Zephyr tree.

The sample can be build for several platforms, the following commands build the
application for the nrf51dk_nrf51422 board.

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/nvs
   :board: nrf51dk_nrf51422
   :goals: build flash
   :compact:

After flashing the image to the board the output on the console shows the
reboot counter and the boards reboots several times to show the reboot counter
is incremented.

Sample Output
