The driver uses #ifdef DEBUG_TIMING in order to conditionally print out timestamped debug messages. Unfortunately it adds the ifdefs all over the usage sites. This patch cleans it up by adding a debug_timestamp() function which is compiled out if DEBUG_TIMING isn't present. This cleans up all the ugly ifdefs in the function logic.
