Two fixes for clock chip drivers:

Browse Source 
- A regression fix for the Designware APB timer. A recent change to the
       error checking code transformed the error condition wrongly so it
       turned into a fail if good condition.
 
     - Fix a clang build fail of the ARM architected timer driver.
