ARM: dts: msm: Disable SMMU error fatal for WLAN on Kona

Currently, after enabling SMMU stage 1, SMMU driver will panic by
default if there is a SMMU fault. Config SMMU driver not to panic
for WLAN so that CNSS driver is able to force device enter RDDM
mode and collect firmware dump after SMMU fault.
