Hi,
Resending this mainly because Marc Zyngier and Mark Rutland raised
concerns about using implementation defined registers and I forgot to Cc
them with the last version. This version, like v4 already, should fix
these concerns. Looking forward to feedback.

Changes since v4:
- Rebase on v5.12-rc5
Changes since v3:
- Add edac-enabled property to make EDAC support optional
Changes since v2:
- drop usage of virtual dt node (Robh)
- use read_sysreg_s instead of open coded variant (James Morse)
- separate error retrieving from error reporting
- use smp_call_function_single rather than smp_call_function_single_async
- make driver single instance and register all 'cpu' hierarchy up front once
Changes since v1:
- Split dt-binding into separate patch
- Sort local function variables in reverse-xmas tree order
- drop unnecessary comparison and make variable bool
