[dpdk-dev] [PATCH v3 1/2] common/octeontx2: move internal symbols to INTERNAL section

[pbhagavatula at marvell.com]

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

Move the internal symbols to INTERNAL sections so that any
change in them is not reported as ABI breakage.

Signed-off-by: Pavan Nikhilesh <pbhagavatula at marvell.com>
---
 v3 Changes:
  - Use `file_name_regexp` insted of `soname_regexp` in supress list for
  backward compatibility of libabigail.

 v2 Changes:
  - Sort version map alphabetically
  - Add libabigail ignore tag for OCTEONTX2
