[PATCH 6/6] docs: efi: add CPER functions to driver-api

[Mauro Carvalho Chehab]

There are two kernel-doc like descriptions at cper, which is used
by other parts of cper and on ghes driver. They both have kernel-doc
like descriptions.

Change the tags for them to be actual kernel-doc tags and add them
to the driver-api documentaion at the UEFI section.
