i.MX: Split the CCM class into an abstract base class and a concrete class

Browse source 
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.
