Problem with system time in lpc176x bsp

[Marcos Díaz]

That patch didn't work,
one reason is that it has a mistake:
in kern_tc.c you defined this macro:

#define _Timecounter_Release(lock_context) \
+  *_ISR_lock_ISR_disable_and_acquire*(&_Timecounter_Lock, lock_context)

I think you meant:

     *_ISR_lock_Release_and_ISR_enable*(&_Timecounter_Lock, lock_context)

The other reason is that as I said, the driver checks for the flag PENDSTSET
of the ICSR register, and I think this approach is wrong, because that flag
goes down when the tick interrupt is attended. I used the solution I
proposed before, but I'm still seeing some errors. I'll let you know what I
find.
