drm/msm/dpu: enable sourcesplit for sc7180/sc7280

According to the vendor dts files, both sc7180 and sc7280 support the
source split mode (using two LMs for a single output). Change these two
platforms to use MIXER_SDM845_MASK, which includes
DPU_MIXER_SOURCESPLIT. Rename MIXER_SC7180_MASK to MIXER_QCM2290_MASK,
since this platform doesn't seem to support source split mode.
