ARM: dts: sh73a0: Correct interrupt type for ARM TWD
The ARM TWD interrupt is a private peripheral interrupt (PPI), and per the ARM GIC documentation, whether the type for PPIs can be set is IMPLEMENTATION DEFINED. For SH-Mobile AG5 devices the PPI type cannot be set, and so when we attempt to set the type for the ARM TWD interrupt it fails. This has gone unnoticed because it fails silently, and because we cannot re-configure the type it has had no impact. Nevertheless fix the type for the TWD interrupt so that it matches the hardware configuration. Based on patches by Jon Hunter for Tegra20/30 and OMAP4.
