bsps/arm: Fix Cortex-M DWT CPU counter.
It is necessary to enable the DWT using a special initialization
sequence before the CYCCNT can be enabled. See for example the
RESET_CYCLE_COUNTER in libbsp/arm/atsam/utils/utility.h.
Note that this problem only occurs if no debugger is connected. A
debugger most likely already enables the necessary module.
