This patch provides a converter class (inherited from V4L2M2MConverter). The DW100 dewarp engine has scaling capabilites and can be used to set crop rectangles in the rkisp1 pipeline handler. Plumbing in the RkISP1 pipeline-handler is done in the subsequent patch. The ConverterDW100 class can be extended later (as additional development) to support the dewarping by setting a dewarp vertex map as well.
