x86/irq: Clean up io_apic.h
Clean up io_apic.h by: 1) moving definition of struct mp_ioapic_gsi into io_apic.c 2) changing mp_pin_to_gsi() and mp_ioapic_gsi_routing() as static 3) removing unused MP_MAX_IOAPIC_PIN 4) removing useless forward declaration 5) removing useless comments Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Tested-by: Joerg Roedel <jroedel@suse.de> Cc: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Cc: David Cohen <david.a.cohen@linux.intel.com> Cc: Sander Eikelenboom <linux@eikelenboom.it> Cc: David Vrabel <david.vrabel@citrix.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Joerg Roedel <joro@8bytes.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Rafael J.
