ARM: tegra: 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 Tegra20/30 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.
