intel/eagleheights: Fix IASL warnings
The eagleheights platform had 3 warnings:
The SIO device needs an _ADR object to specify the address in addition
to the operating region.
Not all the paths through the _OSC method returned a value. According
to the ACPI spec (5.0 & 6.0), bit 2 needs to be set for an unrecognized
GUID.
dsdt.aml 341: Device(SIO) {
Warning 3141 - ^ Missing dependency
(Device object requires a _HID or _ADR in same scope)
dsdt.aml 140: Method (_OSC, 4)
Warning 3115 - ^ Not all control paths return a value (_OSC)
dsdt.aml 140: Method (_OSC, 4)
Warning 3107 - ^ Reserved method must return a value
(Buffer required for _OSC)
- Remove Kconfig default disabling IASL warnings as errors.
