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.
