media: dt-bindings: adv7180: Introduce 'adv,force-bt656-4' property 



Captured NTSC video would be out of sync when using the adv7280 with
the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) need to
be configured properly to ensure BT.656-4 compatibility.

Introduce the 'adv,force-bt656-4' property to allow the ADV7280
behavior to be consistent with the ADV7180, where BT.656-4 timing
is used by default.
