drm/radeon: fix interlaced modes
The viewport needs the frame size, not the field size.
Makes things worse for me.
Before this patch testing with R9270X I see the same as I did with with an
HD4890 in that normal clock modes are almost OK apart from a bit of wrap
around/dup from bottom line to top, low res double clock modes = trash, but
then it's not implemented.
With this patch the screen is far more trashed = top 1/5 shredded and
displaying some of what is in rest of screen. Bottom 4/5 too dim but not
shredded.
FWIW I don't think my TV is "special" as recently I've tested with an intel
chip (bay trail) and all interlaced modes are correct with that.</pre>
