net: designware: look for a child device node for MDIO bus ...

The Designware driver registers a local MDIO bus for each MAC device,
but without setting a device node pointer for the MDIO bus device.  In
this case, mdiobus_register() will use the MDIO bus's parent device node
(if any) as the MDIO device node.

If the MAC device node has a child node compatible with
"snps,dwmac-mdio", let us use that as the MDIO bus device node.
Otherwise, leave the MDIO bus device node pointer set to NULL and carry
on as before.

The upshot is that PHY device nodes can now be placed in an intermediate
node for the MDIO bus instead of having to place them directly in the
Designware MAC device node.

(Tested on a Terasic DE0-Nano-SoC with a suitably modified device tree.)

fs: devfs: implement d_revalidate hook ...

The files in devfs can change withouut the fs layer noticing, so we
have to revalidate dentries before using them.

A failure could be triggered with:

ls /dev/nand0.root.ubi; ubiattach /dev/nand0.root; ls /dev/nand0.root.ubi

The first 'ls' would create a dentry for nand0.root.ubi with no inode
associated since it does not yet exist. 'ubiattach' then creates that
file, but the second 'ls' does not show it since the dentry is not
revalidated and thus no inode is added to that dentry. This patch
fixes this and also the opposite case when a file is removed (for
example with ubidetach).
