    xen: arm: Select ramdisk bootmodule early enough when building dom0
    
    I thought in 0040b649d6df "xen: arm: Only lookup kernel/initrd bootmodule 
once
    while building dom0" that I had identified place_modules as being soon 
enough,
    but I was wrong, since write_properties wants to use it sooner.
    
    Select the initrd boot module in kernel_probe at the same time we select the
    kernel to avoid all this.
