On sc7280 where eDP is the primary display, PSR is causing IGT breakage even for basic test cases like kms_atomic and kms_atomic_transition.

When the special handling of qcom,adreno-smmu was moved into qcom_smmu_create(), it was overlooked that we didn't have all the required entries in qcom_smmu_impl_of_match.

Despite downstream DTS stating otherwise, the PINGPONG block has no registers starting with DPU revision 7.0.0. TEAR registers are gone since DPU 5.0.0 after being moved to the INTF block, and DSC registers are gone since 7.0.0, leaving only the dither sub-block. A future patch, part of the DSC 1.2 series, should disable DSC functions on the PINGPONG block for all DPU >= 7.0.0 hardware.

SM8550 exclusively has a DITHER sub-block inside the PINGPONG block and no other registers, hence the DITHER name of the macro and a corresponding PINGPONG block length of zero.

No hardware beyond kona (sm8250, DPU 6.0.0) defines the TE2 PINGPONG sub-block offset downstream, and according to insiders no DPU >= 5.0.0 hardware has support for it either. Especially since neither downstream nor upstream utilize these registers in any way, remove the erroneous specification from SM8150, SC8180X, SM8250, SC7180, SM8350, SC8280XP and SM8450 to prevent confusion. Note that downstream enables the PPSPLIT (split-FIFO) topology (single LM for 2 PP and 2 INTF) based on the presence of a TE2 block.

Change lm blocks pairs so that lm blocks with the same features are paired together: LM_0 and LM_1 with PP and DSPP LM_2 and LM_5 with PP LM_3 and LM_4 This matches the sdm845 configuration and allows using pp or dspp when 2 lm blocks are needed in the topology.

while binding the code always registers a audio driver, however there is no corresponding unregistration done in unbind. This leads to multiple redundant audio platform devices if dp_display_bind and dp_display_unbind happens multiple times during startup. On X13s platform this resulted in 6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports. Fix this by unregistering codecs on unbind. Signed-off-by:
