Subject: [PATCH 2/2] dt-bindings: display: bridge: sil,sii9022: Add data-lines

The SI9022 HDMI transmitter can be configured with 16, 18, or 24 input
data lines. This commit introduces the data-lines property to the input
endpoint, specifying the number of parallel RGB input pins connected
to the transmitter.
