MLK-11263-2 video: epdc: move setup_waveform_file to board common

Since setup_waveform_file in different boards code have same implementation,
move setup_waveform_file to board common code. Also rename it to
board_setup_waveform_file

This patch also fix a bug when using flush_cache. We should pass
'waveform_buf' to flush_cache, but not a string named 'addr'.
