The DTB and/or the kernel command line may pass 64-bit addresses regardless of kernel configuration, so update arm_add_memory() to take 64-bit arguments independently of the phys_addr_t size. This allows non-wrapping handling of high memory banks such as the second memory bank of APE6EVM (at 0x2_0000_0000) in case of 32-bit phys_addr_t.
