PCI: loongson: Add ACPI init support
Loongson PCH (LS7A chipset) will be used by both MIPS-based and LoongArch-
based Loongson processors. MIPS-based Loongson uses FDT, while LoongArch-
based Loongson uses ACPI.
Add ACPI init support for the driver in pci-loongson.c because it is
currently FDT-only.
LoongArch is a new RISC ISA, mainline support will come soon, and
documentations are here (in translation):
