Implement an ARM delay timer to be used for udelay() on orion legacy
platforms.  This allows us to skip the delay loop calibration at boot.

It also means that udelay() will be unaffected by CPU frequency changes
when cpufreq is enabled on these platforms.

Applied on mvebu/drivers with Acked-by tag from  Andrew Lunn

And, I hope, my tested-by which delayed Andrew's ack until December,
despite the patch being marked as CFT because I wanted _others_ to
test it (which never happened.)
