ASoC: DaVinci: Add hw_param callback for S/PDIF DIT link
On TI DM6467 EVM, S/PDIF DIT codec fails to open as it is unable to install hardware params. This dummy codec has no set_fmt and set_sysclk implementations and calls from the application to these functions cause errors. This patch adds a new hardware params callback function for S/PDIF transciever codec.
