cpufreq/arm-bl-cpufreq: Avoid redundant switching printks
Previously, switch_to_entry() would print a "switching to cluster
n" message to the kernel log even if the system is already on
cluster n.
This patch makes that printk conditional, so that printk only
happens if the call to the hypervisor (and the switch) acctually
occurs.
