[SRU][J:linux-bluefield][PATCH v2 0/1] UBUNTU: SAUCE: mlxbf-ptm: add thermal envelope debugfs node

[Jitendra Lanka]

BugLink: https://bugs.launchpad.net/bugs/2034594

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:
* This change adds additional debugfs node that gets the current thermal
  envelope set in the thermal state machine

[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
* cat /sys/kernel/debug/mlxbf-ptm/temp_envelope shows current thermal
  envelope

[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.
