vexpress: init: Setup cpufreq for TC2

As TC2 is the only vexpress CoreTile so far which can support cpufreq
it's safe to assume the sysfs entries for this don't exists on anything
other than TC2, so poking them is a harmless error on these other
CoreTiles.

We need to revisit this when other vexpress hardware supports cpufreq
but for now, lets just get TC2 working nicely.
