[PATCH AUTOSEL 6.1 32/58] drm/msm/dpu: Add DSC hardware blocks to register snapshot

[Sasha Levin <sashal@kernel.org>]

From: Marijn Suijten <marijn.suijten@somainline.org>

[ Upstream commit a7efe60e36b9c0e966d7f82ac90a89b591d984e9 ]

Add missing DSC hardware block register ranges to the snapshot utility
to include them in dmesg (on MSM_DISP_SNAPSHOT_DUMP_IN_CONSOLE) and the
kms debugfs file.
