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.
