qcacld-3.0: Change system power debugging time stamp to microseconds

Time stamp for profiling system level power issues is currently using
qdf_get_system_timestamp(), which measures in milliseconds. To get more
fine granular data, use qdf_get_log_timestamp_usecs() to measure in
microseconds instead.
