Subject: [PATCH v2 09/18] x86: Make get_ramdisk_{image|size}() global.

In the following patches, we need to call get_ramdisk_{image|size}()
to get initrd file's address and size. So make these two functions
global.

v1 -> v2:
As tj suggested, make these two function static inline in
arch/x86/include/asm/setup.h.
