MIPS: Make init_vdso a subsys_initcall.

Quoting from Jiri Slaby's patch of a similar nature for x86:

    When initrd is in use and a driver does request_module() in its
    module_init (i.e. __initcall or device_initcall), a modprobe
    process is created with VDSO mapping. But VDSO is inited even in
    __initcall, i.e. on the same level (at the same time), so it may
    not be inited yet (link order matters).

Move init_vdso up to subsys_initcall to avoid the issue.
