[PATCH] i386: Restore CONFIG_PHYSICAL_START option

o Relocatable bzImage support had got rid of CONFIG_PHYSICAL_START option thinking that now this option is not required as people can build a second kernel as relocatable and load it anywhere. So need of compiling the kernel for a custom address was gone. But Magnus uses vmlinux images for second kernel in Xen environment and he wants to continue to use it. o Restoring the CONFIG_PHYSICAL_START option for the time being. I think down the line we can get rid of it.
