[U-Boot] [PATCH 8/9] malta: Use I/O accessors for SuperI/O controller

[Paul Burton]

Rather than passing the I/O port base address to the Super I/O code,
switch it to using outb such that it makes use of the I/O port base
address automatically.

Drop the extern keyword to satisfy checkpatch whilst here.
