The Broadcom Brahma-B53 core is susceptible to the issue described by
ARM64_ERRATUM_843419 so this commit enables the workaround to be applied
when executing on that core.
Since there are now multiple entries to match, we must convert the
existing ARM64_ERRATUM_843419 into an erratum list and use
cpucap_multi_entry_cap_matches to match our entries.

The Kryo cores share errata 1009 with Falkor, so add their model
definitions and enable it for them as well.

Allow the user to select the workaround for TX2-219, and update
the silicon-errata.rst file to reflect this.

It looks like the HIP06/07 SoCs have extra bits in their GICD_TYPER
registers, which confuse the GICv3.1 code (these systems appear to
expose ESPIs while they actually don't).
Detect these systems as early as possible and wipe the fields that
should be RES0 in the register.

The documentation is in a format that is very close to ReST format.
The conversion is actually:
- add blank lines in order to identify paragraphs;
- fixing tables markups;
- adding some lists markups;
- marking literal blocks;
- adjust some title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
