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.
