Subject: iommu/arm-smmu: Remove duplicate error message
Git-commit: 34d1b0895dbd10713c73615d8f532e78509e12d9
Patch-mainline: v5.5-rc1
References: bsc#1160135

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message
to platform_get_irq*()"), platform_get_irq() displays an error when the
IRQ isn't found. Remove the error print from the SMMU driver. Note the
slight change of behaviour: no message is printed if platform_get_irq()
returns -EPROBE_DEFER, which probably doesn't concern the SMMU.

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
