[PATCH v4 02/22] x86, microcode: Use common get_ramdisk_image()

[Yinghai Lu <yinghai@kernel.org>]

Use common get_ramdisk_image() to get ramdisk start phys address.

We need this to get correct ramdisk adress for 64bit bzImage that
initrd can be loaded above 4G by kexec-tools.

-v2: fix one typo that is found by Tang Chen
