x86: adjust ramdisk load address
By default, ramdisk load address is defined to 02000000 in env string.
When loading bzImage to 01000000 (default address), there's a chance that
the ramdisk header would be overwritten by the kernel. Thus increase the
gap and make ramdisk load at 04000000 by default and also this patch
introduces a new configuration item CONFIG_RAMDISK_ADDR for this purpose
