Patrick Wildt 8546cfd08a arm64: dts: rockchip: adjust SMMU interrupt type on rk3588
The SMMU architecture requires wired interrupts to be edge triggered,
which does not align with the DT description for the RK3588.  This leads
to interrupt storms, as the SMMU continues to hold the pin high and only
pulls it down for a short amount when issuing an IRQ.  Update the DT
description to be in line with the spec and perceived reality.
