Changes in v3:
- use fdt_generate_phandle() instead of fdtdec_generate_phandle()
- add device tree bindings for /reserved-memory
- add examples to code comments

Changes in v2:
- split fdt_{addr,size}_unpack() helpers into separate patch
- use name at x,y notation only if the upper cell is > 0
- use debug() instead of printf() to save code size
- properly compute number of cells in reg property
- fix carveout size computations, was off by one
- use #size-cells where appropriate
