[U-Boot] [PATCH v3 06/13] fdtdec: Implement carveout support functions

[sjg at google.com]

From: Thierry Reding <treding at nvidia.com>

The fdtdec_get_carveout() and fdtdec_set_carveout() function can be used
to read a carveout from a given node or add a carveout to a given node
using the standard device tree bindings (involving reserved-memory nodes
and the memory-region property).

Changes in v3:
- add examples to code comments

Changes in v2:
- use debug() instead of printf() to save code size
- fix carveout size computations, was off by one
- use fdtdec_get_addr_size_auto_noparent()
