The function fdt_increase_size() increases the size of the device tree by the
given amount. This is useful for any code that wants to add a node or large
property, to avoid the possibility of running out of space. It's much smarter
to have U-Boot increase the size of device tree when it knows it's going to
add data, instead of hoping that the DTS was compiled with the right -p value.
