Andy Shevchenko 7c7bcfeae2 ACPI / x86: boot: Don't setup SCI on HW-reduced platforms
As per note in 5.2.9 Fixed ACPI Description Table (FADT) chapter of ACPI
specification, on HW-reduced platforma OSPM should ignore fields related
to the ACPI HW register interface, one of which is SCI_INT.

Follow the spec and ignore any configuration done for interrupt line
defined by SCI_INT if FADT specifies a HW-reduced platform.

HW-reduced platforms will still be able to use SCI in case it provides
an override record in MADT table.
