common: Show page references after internal links

Browse Source 
The custom RTEMS extension produced quite verbose references like
"Chapter 3 - Section 7 - Bla blub".  This may distract the reading flow.
Use a standard Sphinx option to show page references instead, e.g. "Bla
blub (page 11)".  This has some value for printed out documents.
