Arm Generic Diagnostic Dump and Reset device enables a maintainer to
request OS to perform a diagnostic dump and reset a system via SDEI
event or an interrupt. This patchset adds support for the SDEI path.

I do have a patch to enable the interrupt path as well but I'm holding
it back since AGDI table is missing interrupt configuration fields
(trigger type etc.).

The recently published specification is available at
https://developer.arm.com/documentation/den0093/latest

The patchset was tested on Ampere Altra/Mt. Jade.

The patchset applies on top of
