This patch series extends the AMD HSMP driver to support new AMD Family
1Ah Model 50h-5Fh processors with HSMP protocol version 7.

The series introduces new HSMP messages for enhanced system management and
implements variable-sized metrics table support.

Patch 1 adds New HSMP message definitions for Family 1Ah Model 50h-5Fh
processors, extending the HSMP interface capabilities.
The driver version is bumped to 2.6 to reflect these additions.

Patch 2 implements support for variable-sized metrics tables introduced in
these new processors. Enhance hsmp_metric_tbl_read() with offset support.

The series maintains backward compatibility with existing HSMP
implementations while enabling new functionality for the latest AMD
processors.
