After some rumaging I figured out that the idea behind this is that the
platforms which need those clocksources use 'select $CLOCKSOURCE' which
works despite the 'if COMPILE_TEST'.
The 'if COMPILE_TEST' is there to hide the config option when there is no
platform which needs it and expose it for compile test purposes.
So if your particular platform does not use 'select ARM_TIMER_SP804' then
the right fix is to add it to that platform.
