mfd: Versatile Express config infrastructure
Versatile Express platform has an elaborated configuration system, consisting of microcontrollers residing on the mother- and daughterboards known as Motherboard/Daughterboard Configuration Controller (MCC and DCC). The controllers are responsible for the platform initialization (reset generation, flash programming, FPGA bitfiles loading etc.) but also control clock generators, voltage regulators, gather environmental data like temperature, power consumption etc. Even the video output switch (FPGA) is controlled that way. Those devices are _not_ visible in the main address space and the usual communication channel uses some kind of a bridge in the peripheral block sending commands (requests) to the controllers and receiving responses. It can take up to 500 microseconds for a transaction to be completed, therefore it is important to provide a non-blocking interface to it. This patch adds an abstraction of this infrastructure. Bridge drivers can register themselves with the framework. Then, a driver of a device can request an abstract "function" - the request will be redirected to a bridge referred by thedd "arm,vexpress,config-bridge" property of the device tree node.
