569aad4fcd net: ag71xx: fix mdio subnode support
This patch is syncing driver with actual devicetree documentation:
Documentation/devicetree/bindings/net/qca,ar71xx.txt
|Optional subnodes:
|- mdio : specifies the mdio bus, used as a container for phy nodes
|  according to phy.txt in the same directory

The driver was working with fixed phy without any noticeable issues. This bug
was uncovered by introducing dsa ar9331-switch driver.
Since no one reported this bug until now, I assume no body is using it
and this patch should not brake existing system.

246902bdf5 net: ag71xx: Use GFP_KERNEL instead of GFP_ATOMIC in 'ag71xx_rings_init()'
There is no need to use GFP_ATOMIC here, GFP_KERNEL should be enough.
The 'kcalloc()' just a few lines above, already uses GFP_KERNEL.

a9d41e7b8b net: ag71xx: Slighly simplify code in 'ag71xx_rings_init()'
A few lines above, we have:
   tx_size = BIT(tx->order);

So use 'tx_size' directly to be consistent with the way 'rx->descs_cpu' and
'rx->descs_dma' are computed below.

269b7c5ff7 ag71xx: fix return value check in ag71xx_probe()
In case of error, the function of_get_mac_address() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
