TPDA clocks are voted during TPDA enable and un-voted during TPDA
disable. Read TPDA registers only when TPDA is enabled to avoid
any unclocked access. Add TPDA enable validation checks before
reading TPDA flush registers via sysfs show functions. These validation
checks are already present in sysfs store functions used for making TPDA
flush request.

can clear the flag if timestamp is not required for frequency packets.

Add TPDA and TPDM driver support required for trace, profiling & diagnostic
data collection and retrieval. Monitors are responsible for data set
collection and aggregators are useful for pulling the datasets from one or
more attached monitors and pushing the resultant data out.
