libs: encoder: h264: add refs property

Browse source 
Users can provide the number of reference frame by this property.

The value of the property will be considered as the number of
reference picture list0 and will add 1 reference frame more to the
reference picture list1 internally if b-frame encoding.

If the value provided is bigger than the number of refrence frames
supported in the driver, it will be lowered.
