drm/msm/dpu: Add CWB to msm_display_topology
Currently, the topology is calculated based on the assumption that the
user cannot request real-time and writeback simultaneously. For example,
the number of LMs and CTLs are currently based off the number of phys
encoders under the assumption there will be at least 1 LM/CTL per phys
encoder.
This will not hold true for concurrent writeback as both phys encoders
(1 real-time and 1 writeback) must be driven by 1 LM/CTL when concurrent
writeback is enabled.
To account for this, add a cwb_enabled flag and only adjust the number of
CTL/LMs needed by a given topology based on the number of phys encoders
only if CWB is not enabled.
