If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.

We could end up dereferencing an error pointer when we call
regulator_disable().

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.

sun4i_mdio_reset() does nothing useful and is optional for the MDIO bus
code, so let's just remove it.

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the mdio driver for consistency, and keep the
older one for backward compatibility.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
This covers everything under drivers/net except for wireless, which
has been submitted separately.

Use devm_ioremap_resource instead of of_iomap() and devm_kzalloc()
instead of kmalloc() to make cleanup paths simpler. This patch also
fixes the resource leak caused by missing corresponding iounamp()
of the of_iomap().

The current timeout check is comparing two constant values, so it won't
ever detect a timeout. This patch reworks the affected code a bit so it
has a chance at detecting timeouts correctly.

This patch adds a separate driver for the MDIO interface of the
