media: vidtv: fix build on 32bit architectures

From: Daniel W. S. Almeida <[email protected]>

Fix the following error for builds on 32bit architectures:

ERROR: modpost: "__udivdi3" [drivers/media/test-drivers/vidtv/dvb-vidtv-bridge.ko] undefined!

Which is due to 64bit divisions that did not go through the helpers in linux/math64.h

As vidtv_mux_check_mux_rate was not operational in its current form, drop the entire function while it is not fixed properly.

For now, call vidtv_mux_pad_with_nulls with a constant number of packets to avoid warnings due to unused functions when building this driver.

The 64bit division used in the s302m is not needed, remove them and use a fixed number of frames and a constant PTS increment instead.

---
Changes in v2:

Rework the s302m encoder so that a fixed number of frames and a constant increment value for pts is used. This removes the 64bit division that was making the build fail.
