Rong Zhang 502bba6fbc MIPS: Loongson2ef: Register PCI controller in early stage ...

We are about to set loongson_pci_io_resource.start to 0 and adopt
PCIBIOS_MIN_IO. As the first step, PCI controller needs to be registered
in early stage to make it the root of other resources (e.g., i8259) and
prevent resource conflicts.

Register it in plat_mem_setup() instead of arch_initcall().
