[ARM] orion5x: TS-78xx support for 'hotplug' of FPGA devices
the FPGA on the TS-7800 provides access to a number of devices and so we have to be careful when reprogramming it. As we are effectively turning a bus off/on we have to inform the kernel that it should stop using anything provided by the FPGA (currently only the RTC however the NAND, LCD, etc is to come) before it's reprogrammed. Once reprogramed, we can tell the kernel to (re)enable things by checking the FPGA ID against a lookup table for what a particular FPGA bitstream can provide.

Say 'Y' here if you want your kernel to support the
Technologic Systems TS-78xx platform.
