ARM: vexpress/tc2: implement PM suspend method
This is simplistic for the moment as the expected residency is used to
prevent the shutting down of L2 and the cluster if the residency for
the last man is lower than 5 ms. To make this right, the residency
end time for each CPU would need to be recorded and taken into account.
On a suspend, the firmware mailbox address has to be set prior entering
low power mode.
