software/bios/cmds/cmd_bios: Make crc command 64-bit clean

Browse source 
On 64-bit:

    litex/soc/software/bios/cmds/cmd_bios.c: In function 'crc_handler':
    litex/soc/software/bios/cmds/cmd_bios.c:110:30: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
      printf("CRC32: %08x", crc32((unsigned char *)addr, length));
				  ^

Fix this by using the appropriate types (uintptr_t and size_t) for
memory addresses and sizes, which are defined to 32-bit or 64-bit,
depending on the platform.

Note that the specified length must still be smaller than 4 GiB on
64-bit, or it will be truncated, as the crc32() function is currently
limited to a 32-bit size anyway.
