Replace FSL USB platform code by simple platform driver for
creation of FSL USB platform devices.
The driver creates platform devices based on the information
from USB nodes in the flat device tree. This is the replacement
for old arch fsl_soc usb code removed by this patch. The driver
uses usual of-style binding, available EHCI-HCD and UDC
drivers can be bound to the created devices. The new of-style
driver additionaly instantiates USB OTG platform device, as the
appropriate USB OTG driver will be added soon.

The main purpose of this patch is to pass 'struct spi_device' to the chip
select handling routines. This is needed so that we could implement
full-fledged OpenFirmware support for this driver.
While at it, also:
- Replace two {de,activate}_cs routines by single cs_contol().
- Don't duplicate platform data callbacks in mpc83xx_spi struct.

On MPC837X CPUs Dual-Role USB isn't always available (for example DR
USB pins can be muxed away to eSDHC).
U-Boot adds status = "disabled" property into the DR USB nodes to
indicate that we must not try to configure or probe Dual-Role USB,
otherwise we'll break eSDHC support on targets with MPC837X CPUs.

Does the same for the accompanying MDIO driver, and then modifies the TBI
configuration method. The old way used fields in einfo, which no longer
exists. The new way is to create an MDIO device-tree node for each instance
of gianfar, and create a tbi-handle property to associate ethernet controllers
with the TBI PHYs they are connected to.

The init_phy() function attaches to the PHY, then configures the
SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY
(sort of) and is accessed via the gianfar's MDIO registers, using the
functions gfar_local_mdio_read/write(), which don't do any locking.
The previously attached PHY will start a work-queue on a timer, and
probably an irq handler as well, which will talk to the PHY and thus use
the MDIO bus. This uses phy_read/write(), which have locking, but not
against the gfar_local_mdio versions.
The result is that PHY code will try to use the MDIO bus at the same time
as the SerDes setup code, corrupting the transfers.
Setting up the SerDes before attaching to the PHY will insure that there is
no race between the SerDes code and *our* PHY, but doesn't fix everything.
Typically the PHYs for all gianfar devices are on the same MDIO bus, which
is associated with the first gianfar device. This means that the first
gianfar's SerDes code could corrupt the MDIO transfers for a different
gianfar's PHY.
The lock used by phy_read/write() is contained in the mii_bus structure,
which is pointed to by the PHY. This is difficult to access from the
gianfar drivers, as there is no link between a gianfar device and the
mii_bus which shares the same MDIO registers. As far as the device layer
and drivers are concerned they are two unrelated devices (which happen to
share registers).
Generally all gianfar devices' PHYs will be on the bus associated with the
first gianfar. But this might not be the case, so simply locking the
gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup
code is going to use.
We solve this by having the code that creates the gianfar platform device
look in the device tree for an mdio device that shares the gianfar's
registers. If one is found the ID of its platform device is saved in the
gianfar's platform data.
A new function in the gianfar mii code, gfar_get_miibus(), can use the bus
ID to search through the platform devices for a gianfar_mdio device with
the right ID. The platform device's driver data is the mii_bus structure,
which the SerDes setup code can use to lock the current bus.

The old code assumed there was only one, but the 8572 actually has 3.
Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was
preventing the multiple buses from having different ids. So we only keep
the low 20 bits, which have the interesting info, anyway.

Currently, fsl_i2c_of_init() uses the order of the I2C adapter nodes in the
device tree to enumerate the I2C adapters. Instead, let's check for the
cell-index property and use it if it exists.
This is handy for device drivers that need to identify the I2C adapters by
specific numbers. The Freescale MPC8610 ASoC V2 sound drivers are an example.

This introduces a new device binding for the CPM and other devices on
these boards. Some of the changes include:
1. Proper namespace scoping for Freescale compatibles and properties.
2. Use compatible rather than things like device_type and model
to determine which particular variant of a device is present.
3. Give the drivers the relevant CPM command word directly, rather than
requiring it to have a lookup table based on device-id, SCC v. SMC, and
CPM version.
4. Specify the CPCR and the usable DPRAM region in the CPM's reg property.
Boards that do not require the legacy bindings should select
CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once
all existing boards are converted and tested, the config option can
become default y to prevent new boards from using the old model. Once
arch/ppc is gone, the config option can be removed altogether.
