media: cx231xx: Fix AGC levels for NTSC-M

Windows uses the implemented command sequence to set AGC for NTSC-M.
The previous Linux values work, mostly, but on some embedded
platforms NTSC-M is very unstable. The Windows default values
completely fix any signal stability issues and produce a clear image.
