The below warning appears when the hvc xen driver is compiled without
CONFIG_HVC_XEN_FRONTEND not enabled:
drivers/tty/hvc/hvc_xen.c:333:12: warning: ‘xen_console_remove’ defined but not
used [-Wunused-function]
static int xen_console_remove(struct xencons_info *info)
^
Move the #ifdef CONFIG_HVC_XEN_FRONTEND earlier to only compile
xen_console_remove, xen_cons_free, xen_cons_disconnect_backend when it's
necessary.
