[seL4] Coretex A15 periodic timer interrupts

Hello,

I wonder if the generic timer https://github.com/seL4/util_libs/blob/master/libplatsupport/src/arch/arm/ge... can be extended by timer->periodic timer->handle_irq to be able to run the sel4 testsuite which requires timer IRQ's such as https://github.com/seL4/sel4test/blob/master/apps/sel4test-tests/src/tests/i...

Right now I am able to get timer_get_time(env->timer->timer); by using the generic timer, but I am missing the periodic time and the irq handler for the Coretex A15 generic timer implementation.

Some ideas if there is some tricky way to get it running?

Thanks in advance! - Wladislav Wiebe
