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
requests now.

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.
