V4L/DVB (10176a): Switch remaining clear_user_page users over to clear_user_highpage

Browse source 
Not all architectures provide clear_user_page(), but clear_user_highpage()
is available everywhere at least via the compatibility inline function.

Is this the "trivial patch" that's required for these two drivers?
