media: platform: mtk-mdp3: add support for parallel pipe to improve FPS In some chips, MDP3 has the ability to utilize two pipelines to parallelly process a single frame. To enable this feature, multiple CMDQ clients and packets need to be configured at the same time.

In case of multi-core SCP, this also allows to select a specific core.

media: mtk-mdp3-core: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
