Add the comment for framerate in VAEncMiscParameterFrameRate

Graphics / Video Acceleration / VA-API - Xiang, Haihao [intel.com] - 13 September 2016 17:26 UTC

To express a frame rate, such as 7.5, we have to use 'numerator / denominator'. The high 2 bytes will be used as denominator and the low 2 bytes will be used as numerator.

To keep backward compatible, the low 2 bytes is the real frame rate when the high 2 bytes is 0.
