[PATCH 09/13] dt-bindings: media: ov5640: Add default for synch signals

[Jacopo Mondi <jacopo+renesas@xxxxxxxxxx>]

Add defalt value for the DVP interface synchronism signals.

The default values have been derived from register 0x4740
documentation (datasheet version 2.03)

0x4740 POLARITY CTRL00 default = 0x20
bit 5: pclk polarity = 1 active high
bit 1: HREF polarity = 0 active low
bit 0: VSYNC polarity = 0 active low
