doc-rst: linux_tv: simplify references

There are lots of internal references in the form:
	:ref:`foo <foo>`

Simplify them to be just: :ref:`foo`.

Patch generated via this small script:

for j in $(find . -name '*'); do echo $j; perl -ne 'if (m/\`(\S+)\s*\<(\S+)\>\`/) { if (!($1=~'http') && $1 eq $2) { s,\s*\<(\S+)\>,,; } } print $_' <$j >a && mv a $j; done
