msm: mpq8064: VC report field info that is used by VP

VP assumed that the first field provided was a bottom field, if VP
was incorrect in this assumption it would not properly de-interlace
content. It was also possible for VC to drop a field, when this
happened VP would become out of sync again causing de-interlacing
to be incorrect.
