Subject: [PATCH 5/6] thermal: brcmstb_thermal: Restructure interrupt registration

From: Florian Fainelli <[email-masked]>
Date: Wed, 30 Oct 2019 11:21:31 -0700

If we are successful grabbing the interrupt resource, then register an
interrupt handler, this makes it easier to support the interrupt as
being optional, which is it for 7216.
