Add support for 64-bit addresses/sizes

At the moment, ImageBuilder assumes that all addresses/sizes are
32-bit max. It sets #{address,size}-cells to 0x2 and puts 0x0 as the
value for the first cell. Because of that, we cannot specify
MEMORY_START and MEMORY_END to be above 32-bits (e.g. to place the images
in the upper memory bank).

Add support to properly handle 64-bit addresses/sizes:
 - add function split_into_halves to split the value passed as a first
   argument into upper and lower halves. These are then set as values for
   variables passed respectively as the second and third argument,
 - add function split_addr_size to split address and size and form a
   string to be passed to dt_set as data argument for reg property.
