Rong Zhang 3b8fa431e0 MIPS: Loongson2ef: Register PCI controller in early stage 
[ Upstream commit 6a00c043af ]

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().
