[ Upstream commit 9cf28e41f9f768791f54ee18333239fda6927ed8 ]
While testing the recent suspend and resume regressions I noticed that duovero can still end up losing edge gpio interrupts on runtime suspend. This causes NFSroot easily stopping working after resume on duovero.
Let's fix the issue by using gpio level interrupts for smsc as then the gpio interrupt state is seen by the gpio controller on resume.
