Bug Description
SRU Justification:
[Impact]
Currently, the counters under the clock_measure HW block are not supported by the driver and is a new requirement for calculating performance metrics.
[Fix]
Add support for "clock_measure" block by passing the block info via ACPI. The events monitored by these counters is added to the driver and exposed via a new sysfs sub-directory for this block.
[Test Case]
Read any of the registers listed under the "clock_measure" sub-directory. These fields are read-only and hence all writes will be blocked by the driver.
[Regression Potential]
Can be considered minimal.
