[PATCH WIP 5/6] media: vidtv: Move s302m specific fields into encoder context

[Daniel W. S. Almeida]

From: Daniel W. S. Almeida <dwlsalme...@gmail.com>

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.
