include/nuttx/video/video.h: Move global variable declaration out of header file

Browse Source 
Move global variable declaration out of include/nuttx/video/video.h and into the file where it is initialized.  With some toolchains/environments, declaring globals in header files results in multiply defined symobl errors at link time.  This corrects that build problem.
