ACPICA: Obsolete the acpi_os_derive_pci_id OSL interface
This function is not OS-dependent and has been replaced by acpi_hw_derive_pci_id, which is now in the ACPICA core code. Local implementations of acpi_os_derive_pci_id are no longer necessary and are removed. ACPICA BZ 857. http://www.acpica.org/bugzilla/show_bug.cgi?id=857 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
