5225cd8079 [ARM] 4092/1: i.MX/MX1 CPU Frequency scaling latency definition 
The transition latency has to be defined and reasonably
small to allow on-demand and conservative governors.
The value has been defined according to manual.
The imx_set_target() protected against seen out of range

3c8cd0cce9 [ARM] 3992/1: i.MX/MX1 CPU Frequency scaling support 
Support to change MX1 CPU frequency at runtime.
Tested on PiKRON's PiMX1 board and seems to be fully
stable up to 200 MHz end even as low as 8 MHz.
