This reverts commit caa8422d01e983782548648e125fd617cadcec3f.
It turned out that this commit caused a regression at shutdown / reboot, as the synchronize_irq() calls seems blocking the whole shutdown. Also another part of the change about shuffling the call order looks suspicious; the azx_stop_chip() call disables the CORB / RIRB while the others may still need the CORB/RIRB update.
Since the original commit itself was a cargo-fix, let's revert the whole patch.
You will want to include a link to the bug you may be reintroducing so you have that information for easy reference later.
Also do you know if you fixed the bug in any other way, because our CI hasn't reported that GPF since the patch landed. -Chris
