 rtems: Constify rtems_task_wake_when()

 Add a parameter to _TOD_Validate() to disable the validation of the
 ticks member.

 There are two reasons for this change.  Firstly, in
 rtems_task_wake_when() was a double check for time_buffer == NULL (one
 in rtems_task_wake_when() and one in _TOD_Validate()).  Secondly, the
 ticks member is ignored by rtems_task_wake_when().  This was done with a
 write of zero to the ticks member and thus a modification of the
 user-provided structure.  Now the structure is no longer modified.
 Using a mask parameter is quite efficient. You just have to load an
 immediate value and there are no additional branches in _TOD_Validate().

 Close #4406.
