platform-mc: Add support for sensor unit 'Hertz'

Patch [1] adds the frequency sensor namespace.

This patch makes sure that a numeric sensor is added to frequency
namespace when the PLDM sensor unit is 'Hertz' (from DSP0248).

This patch has been tested for Nvidia Grace CPU, which exposes it's
operating clock frequency as a sensor
