superio/smsc/mec1308: Fix IASL warnings

The SIO device needs to provide an _ADR object with the IO
    address as well as the address in the OperationRegion.

ACPI provides two different Resource Descriptor Macros to describe the
    I/O areas required for a device.  The FixedIO macro is only valid for
    10-bit IO addresses.  Use the IO macro instead.

Thank you to recent IASL that allows for addition in the ASL file.  :)

Fixes these warnings:
    dsdt.aml   2276: Device (SIO) {
    Warning  3141 -           ^ Missing dependency
    (Device object requires a _HID or _ADR in same scope)
    dsdt.aml   2390:    FixedIO (0xa00, 0x34)
    Warning  3060 -                 ^ Maximum 10-bit ISA address (0x3FF)
    dsdt.aml   2394:    FixedIO (0xa00, 0x34)
    Warning  3060 -                 ^ Maximum 10-bit ISA address (0x3FF)

Lumpy now compiles its ASL tables with no warnings.  Re-enable
    Warnings as errors.
