Haven't notice earlier that the other patch went mainline.
EXPAND_GRANULARITY is 1KiB and it is used in expand_buf() if the buffer
has to be increased. I hope that is okay.
All other platforms except prpmc2800 are passing the dtb to fdt_init().
prpmc2800 is reallocating the dtb to a malloced area. I thing I can
remove that part since fdt_init() is doing this anyway.
