When running under KVM accel it is expected to have 'clock-frequency' in the DT. Not having this attribute is too risky for both the machine emulation and userspace. We have a way of telling whether this error scenario might happen or not via kvmppc_read_int_cpu_dt() now being able to report errors. From now on, when running KVM, we will assume that 'clock-frequency' will always be present in the DT.
