ARM: realview: basic device tree implementation This implements basic device tree boot support for the RealView platforms, with a basic device tree for ARM PB1176 as an example. The implementation is done with a new DT-specific board file using only pre-existing bindings for the basic IRQ, timer and serial port drivers. A new compatible type is added to the GIC for the ARM1176. This implementation uses the MFD syscon handle from day one to access the system controller registers, and register the devices using the SoC bus.

ARM: appropriate __init annotation for const data Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.
