There are two identical implementations of of_get_mac_address(), one
each in arch/powerpc/kernel/prom_parse.c and
arch/microblaze/kernel/prom_parse.c.  Move this function to a new
common file of_net.{c,h} and adjust all the callers to include the new
header.

of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code.  Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.

This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead.  A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.

After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.

DMA ops requires that coherent_dma_mask be set properly for a device,
but this was not being done for devices on the MV64x60 that use DMA.
Both the serial and ethernet devices need this or they won't be able
to allocate memory.

Currently, there are two different fields in the
mv643xx_eth_platform_data struct that together describe the PHY
address -- one field (phy_addr) has the address of the PHY, but if
that address is zero, a second field (force_phy_addr) needs to be
set to distinguish the actual address zero from a zero due to not
having filled in the PHY address explicitly (which should mean
'use the default PHY address').

If we are a bit smarter about the encoding of the phy_addr field,
we can avoid the need for a second field -- this patch does that.

For each mv64360 entry in the OpenFirmware database, add the
registration of an of_bus to take care of devices connected to
the MV64x60 asynchronous devices controller.
This change makes it possible for those devices to be detected by
drivers that support the of_platform without having a custom call
for each of them in the board file.

Move mv643xx_eth's static state (ethernet register block base address
and MII management interface spinlock) into a struct hanging off the
shared platform device.  This is necessary to support chips that

I2C parameters freq_m and freq_n are assigned defaults in the code,
but if properties for those parameters are not found in the open
firmware description the init routine returns an error and doesn't
create the platform device.

This changes the code so that it doesn't return an error if the
properties are not found but instead uses the default values.

The mv643xx_eth driver is being modified to support multiple instances
of the ethernet silicon block on the same platform.  Each block contains
a single register bank containing the registers for up to three ports
interleaved within that bank.  This patch updates the PowerPC OF to
platform_device glue code to support multiple silicon blocks, each
with up to three ethernet ports.  The main difference is that we now
allow multiple mv64x60_shared platform_devices to be registered and
we provide each port platform_device with a pointer to its associated
shared platform_device.  The pointer will not be used until the
mv643xx_eth driver changes are committed.

I2C adapter drivers are supposed to handle retries on nack by themselves
if they do, so there's no point in setting .retries if they don't.

As this retry mechanism is going away (at least in its current form),
clean this up now so that we don't get build failures later.
