media: dt-bindings: media: i2c: Add imx327 version to IMX327 bindings

Backport from https://patchwork.linuxtv.org/project/linux-media/list/?series=9930



The imx290 driver can be used for both imx290 and imx327 as they have a
similar register set and configuration. imx327 lacks 8 lanes LVDS and
120 FPS support.
