platform_device_id is used to distinguish between gpt types.

With this the -p option is no longer for parse, but for probe instead.
Using this parses a devicetree given on the command line and probes
the devices found in this tree. Devices which already exist are not
probed again, but instead their device_node is attached to the existing
device.

This adds code to probe devices from a devicetree. Most helper
functions are directly imported from Linux.

Drivers need to get their driver data either from devicetree or the platform
information. It should matter for the driver where this data comes from, so
introduce a common function for it.

It starts the switch and provides basic access to the registers.
This driver could also work with some other Micrel switches, possibly
with some small changes.

It is common for drivers to handle multiple similar devices. On
Linux the driver can distinguish between the devices using the
platform_device_id mechanism. Introduce the same for barebox.

Printing device context normally should be "driver instance:",
but instead we printed the device name twice. This patch fixes
this and as a bonus makes the binary a bit smaller. Instead of
a '@' between driver and instance this function now prints a
whitespace which is a bit more like Linux.

This patch adds a I2C bus on which the I2C devices and drivers register.
This makes it cleaner as I2C devices won't accidently end up probed by
a platform_device driver.

Upcoming patches will put I2C/SPI on their own busses with
spi_register_driver / i2c_register_driver which will only
be available if the subsystem is enabled. We could provide
static inlines, but it wouldn't make much sense to compile
a spi/i2c driver if the corresponding subsystem is disabled.

in commit 2bdc9f57a8 the iomux was synced
with the kernel but this leads to some changes in the PAD_CTRL of some
FEC pins leading to a non working FEC on our cpuimx51 board.
This patch set back the PAD_CTRL of the missing pins to the initial
value.

The stmpe mfds can be connected via i2c and spi. This driver provides the basic
infrastructure for the i2c kind. It can be added as a normal i2c-device in the
board code. To enable functions a platform_data struct has to be provided, that
describes what parts of the chip are to be used.
