drm/msm/dpu: add formats check for writeback encoder
In preparation for adding more formats to dpu writeback add
format validation to it to fail any unsupported formats.
changes in v4:
- change the failure message of the API
drm_atomic_helper_check_wb_connector_state() to a generic
one in case it checks more errors later and moreoever it
already has debug message to indicate its failure
- change the corresponding DPU_ERROR to DPU_DEBUG in-line with
other atomic_check failure messages
changes in v3:
- rebase on top of msm-next
- replace drm_atomic_helper_check_wb_encoder_state() with
drm_atomic_helper_check_wb_connector_state() due to the
rebase
changes in v2:
- correct some grammar in the commit text
