x86/amd_node: Use defines for SMN register offsets

Browse source

There are more than one SMN index/data pair available for software use.
The register offsets are different, but the protocol is the same.

Use defines for the SMN offset values and allow the index/data offsets
to be passed to the read/write helper function.

This eases code reuse with other SMN users in the kernel.
