Gcc 6.1 warns about some unused tables:

drivers/media/pci/zoran/zr36016.c:251:18: warning: 'zr016_yoff' defined but not used [-Wunused-const-variable=]
 static const int zr016_yoff[] = { 8, 9, 7 };
                  ^~~~~~~~~~
drivers/media/pci/zoran/zr36016.c:250:18: warning: 'zr016_xoff' defined but not used [-Wunused-const-variable=]
 static const int zr016_xoff[] = { 20, 20, 20 };
                  ^~~~~~~~~~

Those tables aren't used anywere. So, remove them.
