Video: Update Qualcomm GPU framerate and resolution exceptions

Browse Source 
Windows MediaFoundation report `max_macroblocks_per_second` equals
1944000 on Qualcomm Adreno 690 GPU, which technically should support
3840x2160 up to 60fps or 1920x1080 up to 240fps resolution and
framerate. However, the actual result is, it does support 3840x2160
up to 60fps, but only supports 1920x1080 up to 238fps instead of
240fps.

Update the exception comment and condition so we know better about
this issue, we can't really do much to solve this.
