[PATCH 6/8] cmd: meminfo: widen memory map addresses to phys_addr_t

[Raymond Mao <raymondmaoca@gmail.com>]

From: Guodong Xu <guodong@riscstar.com>

On 32-bit builds 'ulong' is only 32 bits wide, so the memory map
truncates any address or size at or above 4 GiB even though the
columns already allow 13 hex digits. Boards with large DRAM therefore
print wrong bases, sizes and gaps.

Use phys_addr_t for every region address and print it as a 64-bit
value so the map is correct regardless of the build's long width.
