timer: Add a test for timer_timebase_fallback
To test this function, sandbox CPU must set cpu_platdata.timebase_freq on
bind. It also needs to expose a method to set the current cpu. I also make
some most members of cpu_sandbox_ops static.
On the timer side, the device tree property
sandbox,timebase-frequency-fallback controls whether sandbox_timer_probe
falls back to time_timebase_fallback or to SANDBOX_TIMER_RATE.
