Documentation: Begin a RAS section Add some initial RAS documentation. The expectation is for this to collect, among others, all the user-visible features for interaction with the RAS features of the kernel.

Error decoding
Documentation: RAS: Add index and address translation section There are a lot of RAS topic to document, and there are a lot of details for each topic. Prep for this by adding an index for the RAS directory. This will provide a top-level document and table of contents. It also provides the option to build the RAS directory individually using "make SPHINXDIRS=". Start a section on address translation. This will be expanded with details for future translation methods and how they're used in the kernel. Move the error decoding topic to its own section. Links to other error decoding kernel docs will be added.

Error decoding on AMD systems should be done using the rasdaemon tool:
https://github.com/mchehab/rasdaemon/
While the daemon is running, it would automatically log and decode
errors. If not, one can still decode such errors by supplying the
hardware information from the error::
$ rasdaemon -p --status <STATUS> --ipid <IPID> --smca
Also, the user can pass particular family and model to decode the error
string::
$ rasdaemon -p --status <STATUS> --ipid <IPID> --smca --family <CPU Family> --model <CPU Model> --bank <BANK_NUM>
