Public bug reported:

SRU Justification:

[Impact]

mlxbf-ptm is a kernel driver that provides debufgs interface for system
software to monitor Bluefield devices' power and thermal management
parameters.

[Fix]

* This change adds performance improvements to total power reporting
with a single secure monitor call.

[Test Case]

* After installing the kernel module, debugfs entry at 
/sys/kernel/debug/mlxbf-ptm will be created
* monitors/status folder contains read-only parameters reported from the 
Bluefield device

[Regression Potential]

* Minimal - as these are read-only parameters that report Bluefield
device information.

[Other]
* This code is likely to change depending on feedback we received from 
maintainers.

** Affects: linux-bluefield (Ubuntu)
     Importance: Undecided
         Status: New
