[PATCH v2] common: memtop: Fix the return type for find_ram_top

[Venkatesh Yadav Abbarapu]

As the return type is "int" for find_ram_top() function and
returning the "base" which is of phys_addr_t is breaking when the
"base" address is 64-bit. So fix this by updating the return type as
phys_addr_t.
