drm/msm/dpu: link DSPP_2/_3 blocks on SM8350

BugLink: https://bugs.launchpad.net/bugs/2111953

[ Upstream commit 42323d3c9e04c725d27606c31663b80a7cc30218 ]

Link DSPP_2 to the LM_2 and DSPP_3 to the LM_3 mixer blocks. This allows
using colour transformation matrix (aka night mode) with more outputs at
the same time.
