pch_phub: Fix register miss-setting issue
Register "interrupt delay value" is for GbE which is connected to Bus-m of PCIe. However currently, the value is set for Bus-n. As a result, the value is not set correctly. This patch moves setting the value processing of Bus-n to Bus-m. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
