omxvideoenc: delay buffer configuration until component is enabled

Browse source 
No significant change for now. Just delay the input port configuration
of the buffer size related fields (stride, slice height, buffer size)
until the component is activated.
This will allow us to use the actual stride/height of the first input
and so avoid the buffer copying code path in most cases.

Tested on rpi and zynqultrascaleplus.
