Do not request or allocate IRQs in probe for AM654 and J721E so that the user space test script has better control of the devices for which the IRQs are configured. Since certain user space scripts could rely on allocation of IRQ vectors during probe, remove allocation of IRQs only for TI's K3 platform.
