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.
