Subject: [PATCH 0/6] Add support to print sub block registers in dpu hw
 catalog

The purpose of this patch series is to add support to print the registers
of sub blocks in the dpu hardware catalog and fix the order in which all
hardware blocks are dumped for a device core dump. This involves:

1. Changing data structure from stack to queue to fix the printing order
of the device core dump.

2. Removing redundant suffix of sub block names.

3. Removing redundant prefix of sub block names.

4. Eliminating unused variable from relevant macros.

5. Defining names for sub blocks that have not yet been defined.

6. Implementing wrapper function that prints the registers of sub blocks
when there is a need.

Sample Output of the sspp_0 block and its sub blocks for devcore dump:
======sspp_0======
...registers
...
====sspp_0_scaler====
...
...
====sspp_0_csc====
...
...
====next_block====
...
