[PATCH 00/21] drm/msm/dpu: cleanup callbacks, resource manager

In the DPU driver each and every component would provide callbacks, which are mostly static. Other components would use callbacks to receive functionality instead of calling functions directly. Drop (most) of this indirection, replacing with direct function calls. CTL and SSPP blocks are left unconverted for now.

As we are at it, significant part of RM (resource manager) work is dedicated to allocating statically linked components. Each LM is tied to the single PP. Each MERGE_3D can be used by the specified pair of PPs. Each DSPP is also tied to single LM. So instead of allocating them through the RM, get them via static configuration.
