Subject: [PATCH] xen/privcmd: make option visible in Kconfig

This configuration option provides a misc device as an API to userspace.
Make this API usable without having to select the module as a transitive
dependency.

This also fixes an issue where localyesconfig would select
CONFIG_XEN_PRIVCMD=m because it was not visible and defaulted to
building as module.

Signed-off-by: Thomas Weißschuh <linux@...ssschuh.net>

Note: If CONFIG_XEN_PRIVCMD really is only meant to be selected by
XENFS, then the issue can be fixed by removing its "default m"
definition.
