LoongArch: Increase MAX_IO_PICS up to 8
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.
