media: dt-bindings: Merge OV5695 into OV5693 binding

The OV5695 binding is almost the same as the OV5693 binding. The only
difference is 'clock-names' is defined for OV5695. However, the lack of
clock-names is an omission as the Linux OV5693 driver expects the same
'xvclk' clock name.

'link-frequencies' is required by OV5693, but not OV5695, so make that
conditional. Really, this shouldn't vary by device, but we're stuck with
the existing binding use.

The rockchip-isp1 binding example is missing required properties, so it
has to be updated as well.

-* Omnivision OV5695 MIPI CSI-2 sensor
-
-Required Properties:
-- compatible: shall be "ovti,ov5695"
-- clocks: reference to the xvclk input clock
-- clock-names: shall be "xvclk"
-- avdd-supply: Analog voltage supply, 2.8 volts
-- dovdd-supply: Digital I/O voltage supply, 1.8 volts
-- dvdd-supply: Digital core voltage supply, 1.2 volts
