[Buildroot] [git commit] udev: ensure /dev mgmt option is in sync

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=1add7c592bff56c5115997ab9b42e0fd9a5947ca
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

These options should be in sync, both for consistency and because udev
needs devtmpfs enabled in the kernel.

We unfortunately cannot just select BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV
here, as that one selects udev - leading to recursion erors, so instead
we use depends on.
