The two VPUs inside IMX8MQ share the same control block which can be see as a reset hardware block. In order to be able to add the second VPU (for HECV decoding) it will be more handy if the both VPU drivers instance don't have to share the control block registers. This lead to implement it as an independ reset driver and to change the VPU driver to use it.
