[RFC PATCH 4/6] pipeline: rpi: Remove disable_startup_frame_drops config option

[Naushir Patuck]

With the previous change to not drop frames in the pipeline handler,
the "disable_startup_frame_drops" pipeline config option is not used.
Remove it, and throw a warning if the option is present in the YAML
config file.
