[PATCH] clk: raspberrypi: Handle cpufreq device registration failure

[Triet Hoang]

Check the return value of platform_device_register_data() when
registering the raspberrypi-cpufreq device and propagate the error
if registration fails.

This prevents the clock driver from reporting a successful probe
when the cpufreq device could not be registered.
