x86, microcode: Use common get_ramdisk_{image|size}()
In patch1, we change get_ramdisk_image() and get_ramdisk_size()
to global, so we can use them instead of using global variable
boot_params.
We need this to get correct ramdisk adress for 64bits bzImage
that initrd can be loaded above 4G by kexec-tools.
-v2: fix one typo that is found by Tang Chen
