From: Brian Norris <briannorris@chromium.org>
The "arm,no-tick-in-suspend" property was introduced to note
implementations where the system counter does not quite follow the ARM
specification that it "must be implemented in an always-on power
domain".
Particularly, RK3399's counter stops ticking when we switch from the
24MHz clock to the 32KHz clock in low-power suspend, so let's mark it as
such.
