of: Don't allow __of_attached_node_sysfs() without CONFIG_SYSFS ...
[ Upstream commit 6211e9cb2f8faf7faae0b6caf844bfe9527cc607 ]
Trying to boot without SYSFS, but with OF_DYNAMIC quickly
results in a crash:
[ 0.088460] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000070
[...]

While not having sysfs isn't a very common option these days,
it is still expected that such configuration would work.
Paper over it by bailing out from __of_attach_node_sysfs() if
CONFIG_SYSFS isn't enabled.
