6.13-stable review patch. If anyone has any objections, please let me know.

From: Huacai Chen chenhuacai@loongson.cn
commit ec105cadff5d8c0a029a3dc1084cae46cf3f799d upstream.
Begin with Loongson-3C6000, the number of PCI host can be as many as 8 for multi-chip machines, and this number should be the same for I/O interrupt controllers. To support these machines we also increase the MAX_IO_PICS up to 8.
