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

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.

* Changed macro names to match TRM where possible
* Made programmers model macro scheme consistent
* Dropped XADC_ZYNQ_ prefix on local macros
* Fix ALM field width
* Update threshold-comparison interrupts in _update_ints()
* factored out DFIFO pushes into helper. Renamed to "push/pop"

Send a protocol version as the first message from server, clients must

QEMUs should be fine with this change in the protocol since they
overrides their own vm_id on reception of an id associated to no

stm32f2xx_SYSCFG: Add the stm32f2xx SYSCFG

This patch adds the stm32f2xx System Configuration
Controller. This is used to configure what memory is mapped
at address 0 (although that is not supported) as well
as configure how the EXTI interrupts work (also not
supported at the moment).

This device is not required for basic examples, but more
complex systems will require it (as well as the EXTI device)
