To properly deactivate physical eSPI routed to a domain and allow them to
be retriggered after the initial trigger, the LR needs to be updated. The
current implementation ignores interrupts outside the range specified by
the mask 0x3FF, which only covers IRQ numbers up to 1023. To enable
processing of eSPI interrupts, this patch updates the mask to 0x1FFF.
