x86, acpi/irq: Define gsi_end when X86_IO_APIC is undefined 

My recent changes introducing a global gsi_end variable
failed to take into account the case of using acpi on a system
not built to support IO_APICs, causing the build to fail.

Define gsi_end to 15 when CONFIG_X86_IO_APIC is not set to avoid
compile errors.
