1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be
converted over to mdiobus_{alloc,free}().
2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its
struct fixed_mdio_bus and then use container_of() to go from the
former to the latter. Since mii bus structures are no longer
embedded, we need to do something like use the mii bus private
pointer to go from mii_bus to fixed_mdio_bus instead.

In preparation of giving mii_bus objects a device tree presence of
their own, rename struct mii_bus's ->dev argument to ->parent, since
having a 'struct device *dev' that points to our parent device
conflicts with introducing a 'struct device dev' representing our own
device.

Having the id field be an int was making more complex bus topologies
excessively difficult. For now, just convert it to a string, and
change all instances of "bus->id = val" to
snprintf(id, MII_BUS_ID_LEN, "%x", val).

Fix up the module information for gpio-mdio, it wouldn't load
because of lacking license, and wouldn't auto-load because of missing
MODULE_DEVICE_TABLE.

There will be more product numbers in the future than just PA6T-1682M,
but they will share much of the features. Remove some of the explicit
references and compatibility checks with 1682M, and replace most of them
with the more generic term "PWRficient".

Misc cleanups of mdio_gpio:
* Better error handling/unrolling in case of init/alloc failures
* Go through child nodes and get their interrupts instead of using
hardcoded values
* Remap the GPIO registers at module load/driver init instead of during probe
* Coding style and other misc cleanups

We no longer initialise the name and owner fields of the
of_platform_driver, but use the fields of the embedded device_driver's
name field instead.
