Fix source code using Windows newline

[OttoWinter]

Description:

The developer documentation states:

• Line separator should be set to LF.

This PR converts all source files to using Unix newlines \n instead of Windows newlines \r\n. You can replicate this by running

find homeassistant/ tests/ -name '*.yml' -o -name '*.py' -type f -print0 | xargs -0 perl -pi -e 's/\r\n|\n|\r/\n/g'

Checklist:

• The code change is tested and works locally.
