media: i2c: max9286: Rename MAX9286_DATATYPE_RAW11 to RAW12
The MAX9286_DATATYPE_RAW11 value is used to configure the MAX9286 for
11-bit or 12-bit input data. While 11-bit data is supported on the GMSL
side, CSI-2 doesn't have a RAW11 format. 11-bit data is transferred over
CSI-2 as RAW12. Rename the macro accordingly to avoid confusion.
