MISR support is the debug feature present in Snapdragon chipsets. At the layer mixer and interfaces, MISR algorithm can generate CRC signatures of the pixel data which can be used for validating the frames generated. Since there are no clients for this feature, strip down the support from the driver.

Destination scaling(DS) is a Snapdragon hardware feature to scale up the display ROI after layer blending. DPU driver doesn't support programming of DS blocks yet. This change cleans up the residual code present in catalog and RM for DS block handling. Support for the same can be added back when the feature is formally implemented.

RM maintained a redundant definition for display topology to identify the no. of hw blocks needed for a display and their hardware dependencies. This information can be implicitly deduced from the msm_display_topology structure available in RM reserve request. In addition to getting rid of the redundant topology, this change also removes the topology name enums and their usages.

changes in v4: - remove the topology name enum entirely (Sean) changes in v5: - remove RM topology definition and their references (Sean) - Implement helper for dual mixer CRTC (Sean) changes in v6: - avoid heap memory for topology (Sean)
