Add devicetree binding for the Sony IMX415 CMOS image sensor.

Signed-off-by: Michael Riesch <[e-mail]>
---
v3:
 - move description from clock-names to clocks
 - drop clock-names property
 - drop "link-frequencies: true" in endpoint description

v2:
 - fix reference in port (must be /$defs/port-base)
 - describe data-lanes in more detail
 - remove unexpected property clock-lanes from example
 - sort properties in example alphabetically

+description: |-
+  The Sony IMX415 is a diagonal 6.4 mm (Type 1/2.8) CMOS active pixel type
+  solid-state image sensor with a square pixel array and 8.46 M effective
+  pixels. This chip operates with analog 2.9 V, digital 1.1 V, and interface
+  1.8 V triple power supply, and has low power consumption.
+  The IMX415 is programmable through I2C interface. The sensor output is
+  available via CSI-2 serial data output (two or four lanes).
