[dpdk-dev] [PATCH v3] doc: fix PDF build of bbdev prog guide

[Thomas Monjalon <thomas@monjalon.net>]

Some machine (like on dpdk.org) may fail to build the prog guide PDF
because of a table characher being "+" instead of "|".

Some figure references are also fixed with automatic numbering.

Fixes: 3f3f608142cf ("doc: update bbdev guide for 5GNR operations")

v3: fix only the bad character and keep complex table (Thomas)
v2: try simpler table and fix figure refs (Nicolas)
v1: remove some table rows (Thomas)
