[PATCH 3/5] ACPI / x86: Export acpi_[un]register_gsi()

["Rafael J. Wysocki" <rjw@sisk.pl>]

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

These functions might be called from modules as well so make sure
they are exported.

In addition, implement empty version of acpi_unregister_gsi() and
remove the one from pci_irq.c.
