x86/acpi: Handle SCI interrupts above legacy space gracefully
Platforms which support only IOAPIC mode, pass the SCI information above
the legacy space (0-15) via the FADT mechanism and not via MADT.
In such cases mp_override_legacy_irq() which is invoked from
acpi_sci_ioapic_setup() to register SCI interrupts fails for interrupts
greater equal 16, since it is meant to handle only the legacy space and
emits error "Invalid bus_irq %u for legacy override".
Add a new function to handle SCI interrupts >= 16 and invoke it
conditionally in acpi_sci_ioapic_setup().
The code duplication due to this new function will be cleaned up in a
separate patch.
