Patch to remove limit on v4l2src framerate

The current implementation of v4l2 has a hard-coded limit of 100 fps for v4l2
devices. This limits certain applications that may require an even higher
framerate and it also limits cameras with hardware cropping being applied to
them, which can also lead to framerates higher than 100. 

This patch remedies this issue. It first sets the maximum possible framerate to
G_MAXINT/1 to ensure that any future application needing higher framerates is
not capped. This patch also changes the default framerate so it is set to 100,
as it would be for all applications that do not set a framerate before this
patch.
