Revert "drm/msm/dpu: try reserving the DSPP-less LM first"

This reverts commit 42f62cd79578 ("drm/msm/dpu: try reserving the
DSPP-less LM first"). It seems on later DPUs using higher LMs require
some additional setup or conflicts with the hardware defaults. Val (and
other developers) reported blue screen on Hamoa (X1E80100) laptops.
Revert the offending commit until we understand, what is the issue.
