If the guts variable is NULL, it indicates there is error in dts or kernel.
We should fix the error, rather than ignore it.

And that's why there's a warning message.  Crashing the kernel is not 
going to fix anything.

This error likely crashes the kenel somewhere.

Moreover, if smp_85xx_ops.give/take_timebase is NULL, kernel can not do the timebase sync.

Is that necessary for the kernel to boot?

No. But in the cpu hotplug context, we need do the timebase sync.
