xen: use generated hypercall symbols in arch/x86/xen/xen-head.S
Instead of manually list each hypercall in arch/x86/xen/xen-head.S use the auto generated symbol list. This also corrects the wrong address of xen_hypercall_mca which was located 32 bytes higher than it should. Symbol addresses have been verified to match the correct ones via objdump output.
