MDST is a ntuple inside SPIRAH. Its just a interface to pass memory ranges
to be captured as part of dump to FSP/Hostboot. Today OPAL is using MDST
ntuple to pass list of memory region (mostly OPAL console and host dmesg)
to be collected as part of SYSDUMP. Soon we are going to support OPAL MPIPL
feature (aka Memory Preserving IPL). Even MPIPL uses MDST/MDDT table.
Hence rename files based on feature instead of some table name:
- fsp-mdst-table.c -> fsp-sysdump.c
- fsp-mdst-table.h -> opal-dump.h (This will cater both SYSDUMP and MPIPL)
- Rename structure -> dump_mdst_table -> mdst_table
This patch does renaming and header file adjustment. No functionality changes.

Use Software Package Data Exchange (SPDX) to indicate license for each
file that is unique to skiboot.
At the same time, ensure the (C) who and years are correct.

This also means we use proper conversions in fsp-mdst-table.c
This means no actual change for skiboot as it's BE.

Rather than have DUMP_REGION_HOST_START and (unused) OPAL_DUMP_REGION_HOST_START
let's use the defines we have in opal.h as this is API that just happens
to match with what FSP expects.

- Better function naming
- Better macro naming
- Re-ordered function variables
- calculate max_mdst_entry after allocating memory
for mdst table.
No change in functionality.
