Bug Description
SRU Justification:
[Impact]
Currently, the mlxbf-pmc driver supports only BlueField-1 and BlueField-2 devices. BlueField-3 is not supported.
[Fix]
Add support for BlueField-3 devices by adding new access mechanism for programming and reading counter values as in the new design, along with the list of supported events in each HW block in BlueField-3.
[Test Case]
Previously, the driver would not be loaded when the OS is loaded on a BlueField-3 card. With the fix, the driver should get loaded and create sysfs entries as a hwmon device under /sys/class/
[Regression Potential]
The ACPI table needs to be in sync with this change since it depends on newly introduces parameters such as mss_enable and llt_enable, which were not present earlier.
