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().
Fixes: ae81aad5c2e1 ("MIPS: PCI: Use pci_enable_resources()")

As platforms are moving to COMMON_CLK in general, loongson2ef stuck out as something that has a private implementation but does not actually use it except for setting the frequency of the CPU itself from the loongson2_cpufreq driver. Change that driver to call the register setting function directly and remove the rest of the stub implementation.
