Subject: [PATCH 10/11] drm/msm/dpu: tweak lm pairings in msm8998 hw catalog

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. In the previous config the
reservation code could never find an lm pair without a matching feature
set.
