Kuppuswamy Sathyanarayanan ba16fb47e8 powercap: intel_rapl_tpmi: Remove FW_BUG from invalid version check 
[ Upstream commit c7d54dafa0 ]

On partitioned systems, multiple TPMI instances may exist per package,
but RAPL registers are only valid on one instance since RAPL has
package-scope control. Other instances return invalid versions during
domain parsing, which is expected behavior on such systems.

Currently this generates a firmware bug warning:

  intel_rapl_tpmi: [Firmware Bug]: Invalid version

Remove the FW_BUG tag, downgrade to pr_debug(), and update the message
to clarify that invalid versions are expected on partitioned systems
where only one instance can be valid.
