include: fdtdec: decouple fdt_addr_t and phys_addr_t size
The DT specification supports CPUs with both 32-bit and 64-bit addressing
capabilities. In U-boot the fdt_addr_t and phys_addr_t size are coupled
by a typedef. The MTD NAND drivers for 32-bit CPU's can describe partitions
with a 64-bit reg property. These partitions synced from Linux end up with
the wrong offset and sizes when only the lower 32-bit is passed.
Decouple the fdt_addr_t and phys_addr_t size as they don't necessary
match.
