Since atclk is enabled after pclk during the probe phase, this commit maintains the same sequence for the runtime resume flow.
which is also the exact opposite of the suspend flow as expected.

These also matches the clock initialization sequence during probe() via the new helper coresight_get_enable_clocks().
LGTM.
