drm/msm/dpu: provide DSPP and correct LM config for SDM670
[ Upstream commit 9a20f33495bfd45ca6712213f30697f686d0b6fd ]
On SDM670 the DPU has two DSPP blocks compared to 4 DSPP blocks on
SDM845. Currently SDM670 just reuses LMs and DSPPs from SDM845. Define
platform-specific configuration for those blocks.
