configs: vexpress: Enable TC2 power management options

Browse Source 
Note, for the sake of a faster boot and better performance, we default
to maximum CPU clock frequency (CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE)
and will rely on user-side scripts on Android and Ubuntu to change this
as appropriate for big.LITTLE power saving. E.g. changing LITTLE cores
to 'ondemand'.
