[PATCH] soc: fujitsu: Add A64FX diagnostic interrupt driver

[hasegawa-hitomi at fujitsu.com]

Hi Greg, Arnd, and Sumit,

Thank you for your comments and information. I did not know there is 
already a related patch.
I will test Sumit's v2 patch and reply there with the results later. Also, I
will make the v2 patch, based on that patch.

Thank you
Hitomi Hasegawa
