x86/amd_node: Add support for debugfs access to SMN registers
There are certain registers on AMD Zen systems that can only be accessed

Introduce a new interface that provides debugfs files for accessing SMN. As
this introduces the capability for userspace to manipulate the hardware in
unpredictable ways, taint the kernel when writing.
