This patch reworks the zcrypt device driver so that the set_fs() invocation is not needed any more. Instead there is a new flag bool userspace passed through all the functions which tells if the pointer arguments are userspace or kernelspace. Together with the two new inline functions z_copy_from_user() and z_copy_to_user() which either invoke copy_from_user (userspace is true) or memcpy (userspace is false) the zcrypt dd and the AP bus now has no requirement for the set_fs() functionality any more.
