[0/3] AMD SMCA Updates

Message

Hi all,

This set adds supports for SMCA changes in future AMD systems.

Patch 1 adds an "unknown" bank type so that sysfs initialization issues
can be avoided on systems with new bank types.

Patch 2 adds new bank types and error descriptions used in future AMD
systems.

Patch 3 adjusts how SMCA bank information is cached. Future AMD systems
will have different bank type layouts between logical CPUs. So having a
single system-wide cache of the layout won't be correct.

Thanks,
Yazen
