[PATCH 2/3] arm64: dts: fvp: Add system timer for broadcast during CPU idle

[Sudeep Holla]

Introduce a system-level timer node in the FVP device tree to act as
a broadcast timer when CPUs are in context losing idle states where
the local timer stops on entering such low power states.

This change complements recent CPU idle state additions.
