[PATCH v5 08/22] media: rzg2l-cru: Use MIPI CSI-2 data types for ICnMC_INF definitions

The INF field in the ICnMC register accepts data type codes as specified
in the MIPI CSI-2 v2.1 specification. This patch introduces the
`ICnMC_INF()` macro to use the MIPI CSI-2 data types, which are available
in the `media/mipi-csi2.h` header.
