Set crop params to ANative Window during Initialization.

The native_window_set_crop() is called when port reconfig event callback comes from decoder's and
crop parameters are changed from default getconfig() OMX_IndexConfigCommonOutputCrop values.
Since the default crop params are same as port reconfig crop params, the native_window_set_crop()
is not called, hence resulting in displaying the whole frame(paddedWidth x paddedHeight).
By calling native_window_set_crop() during initilaization of output port of decoder ensures
in setting up ANative window to crop region.
