Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

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.

Scan the device tree for i2c devices, check their "compatible" property
against a hard-coded table, and, if found, register with i2c boardinfo.
This provides the infrastructure needed to find i2c devices in the
device tree and register them with the i2c subsystem.
This and the following commit let the linkstation work with the new i2c
API and thus fix a regression.

The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay. So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII. This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.

Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as
of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.
To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.

The fs_no mean used to be fs_enet driver driven, hence it was an
enumeration across all the possible fs_enet "users" in the SoC. Now, with
QE on the pipeline, and to make DTS descriptions more clear, fs_no features
relevant SoC part number, with additional field to describe the SoC type.
Another reason for that is now not only fs_enet is going to utilize those
stuff. There might be UART, HLDC, and even USB, so to prevent confusion and
be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were
updated in that concern, as well as the relevant DTS.

The stuff below cleans up the code attempting to remap the whole cpm2_immr
early, as well as places happily assuming that fact. This is more like the 2.4
legacy stuff, and is at least confusing and unclear now.
To keep the world comfortable, a new mechanism is introduced: before accessing
specific immr register/register set, one needs to map it, using cpm2_map(<reg>),
for instance, access to CPM command register will look like
volatile cpm_cpm2_t *cp = cpm2_map(im_cpm);
keeping the code clear, yet without "already defined somewhere" cpm2_immr.
So far, unmapping code is not implemented, but it's not a big deal to add it,
if the whole idea makes sense.
