media: vidtv: Move s302m specific fields into encoder context
A few fields used only by the tone generator in the s302m encoder are stored in struct vidtv_encoder. Move them into struct vidtv_s302m_ctx instead. While we are at it: fix a checkpatch warning for long lines. Signed-off-by: Daniel W. S.
