Subject: [PATCH 5.16 0660/1017] pinctrl: renesas: r8a77470: Reduce size for narrow VIN1 channel

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit 9e04a0eda84fccab0ac22a33825ad53f47c968c7 ]

The second video-in channel on RZ/G1C has only 12 data lanes, but the
pin control driver uses the vin_data union, which is meant for 24 data
lanes, thus wasting space.

Fix this by using the vin_data12 union instead.

This reduces kernel size by 96 bytes.
