[U-Boot] [PATCH] [RFC] memsize.c: adapt get_ram_size() for address spaces >32 bit

[Wolfgang Denk]

get_ram_size() used to use "long" data types for addresses and data,
which in limited it to systems with less than 4 GiB memory. As more
and more systems are coming up with bigger memory resources, we adapt
the code to use phys_addr_t / phys_size_t data types instead.

Note: this is only minimally tested - I just compiled a dozen of ppc
boards with it without appearent problems. Please review and test
carefully.
