Markus Linnala 9127219358 policy: interfaces: doc: indent param blocks consistently 
There is more than 5000 parameter documentations. Only about 300 are
differently done. Change them to be consistently indented.

param with one space
and content inside with one tab

This was done with:

sed -ri '
/^##[[:space:]]*<param/,/^##[[:space:]]*<[/]param>/{
	s/^##[[:space:]]*/##\t/;
	s/^##[[:space:]]*(<[/]?summary)/##\t\1/;
	s/^##[[:space:]]*(<[/]?param)/## \1/;
