sandy/ivy: Fix PIRQs on Chromebooks 

This partially reverts commit 33b535f1. After this commit, samsung/lumpy had its
internal USB EHCI controller broken, with no assigned IRQ.

PIRQA-PIRQH may be wired as edge-triggered interrupts, making them exclusive
for the GPIO to use. They cannot be used for PCI devices at the same time.
