Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.
Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.

Mostly this is whitespace/minor changes. But there are a few new
features:
- fdt_size_cells() and fdt_address_cells()
- fdt_resize()

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.
