We have some inconsistency where multiple errata for the same component
share the same Kconfig workaround; some are one ID per line, some are
smooshed together, and some are entirely separate entries. Standardise
on the single entry, one ID per line format so that things render nice
and consistently in the HTML docs, and it's simple and clear to add new
IDs to existing workarounds without churning the table too much.

One last tilt at this windmill - at least I did remember! :)
