Subject: [PATCH 1/2] ACPI, x86: export acpi_[un]register_gsi()

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

These functions might be called from modules as well so make sure they are
exported. In addition we implement empty version of acpi_unregister_gsi() and
remove the one from pci_irq.c.

Although there are no modules that use this currently, we are working on
ACPI 5 device enumeration support that is going to use these functions and
some of that code can be compiled as a module.
