The IMX_CCM class is now the base abstract class that is used by EPIT and GPT timer implementation. IMX31_CCM class is the concrete class implementing CCM for i.MX31 SOC. For now the i.MX25 continues to use the i.MX31 CCM implementation. An i.MX25 specific CCM will be introduced in a later patch. We also rework initialization to stop using deprecated sysbus device init.
