[PATCH] venus: enc: fix enum_frameintervals

[Stanimir Varbanov]

This ixes an issue when setting the encoder framerate because of
missing precision. Now the frameinterval type is changed to
TYPE_CONTINUOUS and step = 1. Also the math is changed when
framerate property is called - the firmware side expects that
the framerate one is 1 << 16 units.
