powerpc/85xx: verify the device tree before booting Linux
Introduce ft_verify_fdt(), a function that is called after the device tree
has been fixed up, that displays warning messages if there is a mismatch
between the physical addresses of some devices that U-Boot has configured
with what the device tree says the addresses are.
This is a particular problem when booting a 36-bit device tree from a
32-bit U-Boot (or vice versa), because the physical address of CCSR is
wrong in the device tree. When the operating system boots, no messages are
displayed, so the user generally has no idea what's wrong.
