Add a helper routine to depth-search the device tree for a node with a matching 'compatible' property. This probably has a short half-life (as do most of the fdt_ functions), but it helps solve some near-term needs until we work out the larger problems of device instantiation order versus the order of things in the fdt data.

Make the memory size returned from fdt_get_mem_regions a 64-bit type. This is the physical memory size so may be larger than a u_long can hold, e.g. on ARM with LPAE we could see an address space of up to 40 bits. On ARM u_long is only 32 bits so the memory size will be truncated, possibly to zero. Reported by: bz Sponsored by: ABT Systems Ltd
