pch_phub: Fix register miss-setting issue
commit 20ae6d0b307963416db0e8433602e5d5c95e942b upstream.
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.
