PCI: Add pcie acs and no-bus-reset quirk for mucse Nics

mucse inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8KXIX


CVE: NA

------------------------------------

1. Some MUCSE N10/N400 chips do not support bus/hot reset. The PCIE
automatically disables LTSSM when Secondary Bus Reset is received and
the device stops working. Prevent bus reset for these devices.

2. Some MUCSE N10/N400 chips may be multi-function devices, but the
hardware does not advertise ACS capability. Add an ACS quirk for these
chips NICS so the functions can be in independent IOMMU groups.
