[PATCH 04/13] realtek: use fixed-clock as CPU clock

[Sander Vanheule]

CPU clock definition in devicetree should be specified per CPU, not in
the cpus node. This modification causes plat_init_time() to not find the
CPU frequency in the devicetree any more, but it can fall back to the
(identical) default.
