zephyr: Define CONFIG_HAS_TASK_PD_INT if needed
zephyr: Define CONFIG_HAS_TASK_PD_INT if needed

ECOS uses this option to indicate whether any PD_INT (Power Delivery
Interrupt) task is running. We must define it the same way for Zephyr
so that the interrupt handler runs as expected.

Define it if the PD_INT port 0 is active, since that means there is at
least one task active.
