Revert "PCI: loongson: Add more devices that need MRRS quirk"

Browse Source 
This reverts commit faa050d2ff which is
commit c768f8c5f40fcdc6f058cc2f02592163d6c6716c upstream.

It breaks the Android kernel abi and it not needed for any Android
devices at this time.  If it is needed, it can be brought back in an
ABI-safe way.
