watchdog: intel-mid_wdt: Postpone IRQ handler registration till SCU is ready
[ Upstream commit f285c9532b5bd3de7e37a6203318437cab79bd9a ]
When SCU is not ready and CONFIG_DEBUG_SHIRQ=y we got deferred probe followed
by fired test IRQ which immediately makes kernel panic. Fix this by delaying
IRQ handler registration till SCU is ready.
