drm/msm/dpu: Remove redundant prefix/suffix in name of sub-blocks

For a device core dump, the registers of sub-blocks are printed under a
title formatted as <mainBlkName_sblkName>. For example, the csc sub-block
for an SSPP main block "sspp_0" would be printed "sspp_0_sspp_csc0". The
title is clearly redundant due to the duplicate "sspp" and "0" that exist
in both the mainBlkName and sblkName. To eliminate this redundancy, remove
the secondary "sspp" and "0" that exist in the sub-block name by
elimanting the "sspp_" prefix and the concatenation of "num" that results
in the redundant "0" suffix. Remove num parameter altogether from relevant
macros as a consequence of it no longer being used.
