ARM: dts: rk3288: add arm,cpu-registers-not-fw-configured

This will enable use of physical arch timers on rk3288, where each core comes out of reset with a different virtual offset. Using physical timers will help with SMP booting on coreboot and older u-boot and should also allow suspend-resume and cpu-hotplug to work on all firmwares. Firmware which does initialize the cpu registers properly at boot and cpu-hotplug can remove this property from the device tree.
