Minghuan Lian a31e3ef83b libfdt: Add support for appending the values to a existing property
Some properties may contain multiple values, these values may need
to be added to the property respectively. this patch provides this
functionality. The main purpose of fdt_append_prop() is to append
the values to a existing property, or create a new property if it
dose not exist.
