can: mcp251x: Don't use pdata->model for chip selection anymore
Since commit e446630c960946b5c1762e4eadb618becef599e7, i.e. v2.6.35-rc1, the mcp251x chip model can be selected via the modalias member in the struct spi_board_info. The driver stores the actual model in the struct mcp251x_platform_data. From the driver point of view the platform_data should be read only. Since all in-tree users of the mcp251x have already been converted to the modalias method, this patch moves the "model" member from the struct mcp251x_platform_data to the driver's private data structure.
