drm/msm/dpu: Bind pingpong block to intf on active ctls in cmd encoder
As per the specification of DPU_CTL_ACTIVE_CFG the configuration of
active blocks should be proactively specified, and the pingpong block is
no different.
The downstream display driver [1] confirms this by also calling
bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always
entered, as setup_intf_cfg - unlike this mainline dpu driver that
combines both behind the same function pointer - is left NULL in favour
of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set.
This solves continuous timeouts on at least the Qualcomm sm6125 SoC:
[drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout
[drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1
[drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0
In the same way this pingpong block should also be unbound followed by
an interface flush when the encoder is disabled, according to the
downstream display driver [2].
