On DPU 13 the SSPP block is only 0x84 long and the fetch registers
(source address, size, format, multirect) live in the rec0/rec1
sub-blocks at 0x1000 and 0x3000. The snapshot dumps the SSPP block and
its scaler and CSC sub-blocks, but not rec0/rec1, so the plane fetch
state is missing from the devcoredump and from debugfs dri/N/kms.
Add the rec0/rec1 sub-blocks to the snapshot.
Tested on a Lenovo Legion Tab Y700 gen 5 (SM8850).
