HACK: ARM: Take only initrd/serialno from ATAGS
The kernel command line and memory information from the Samsung
bootloader is useless. On the other hand, it's necessary to know
where it has loaded the ramdisk (and how large it is).
Ignore the cmdline/memory atags for now and only read the
initrd/serial tags.
