Subject: [PATCH 13/16] arch: x86: xen: Add prototype for xen_start_kernel in enlighten.c

enlighten.c defines xen_start_kernel which is used only in this
file and is not defined in any header file. So add a proto-
type for the same above the function definition.

This satisfies the -Wmissing-prototypes gcc warning:
arch/x86/xen/enlighten.c:1534:34: warning: no previous prototype for ‘xen_start_kernel’ [-Wmissing-prototypes]
