Bug Description
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/
* 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.
