[PATCH 08/11] ARM: shmobile: sh73a0 dtsi: Add Cortex-A9 TWD node

From: Geert Uytterhoeven <geert+renesas at glider.be>
Add a node for the Private Timer and Watchdog, as found in the Cortex-A9
MPCore.
Without this, there's no clocksource available during early kernel
initialization, before cmt1 is initialized, leading to a lock-up if
CONFIG_CPU_IDLE=y.
