98ba16bb22 ARM: nomadik: push ethernet down to board
The SoC file defines the location and type of the ethernet
adapter, this should be in the per-board file, as it is by no
means necessary to have an ethernet adapter connected to this
memory space.

3181788c3a ARM: nomadik: fix up double inversion in DT
The GPIO pin connected to card detect was inverted twice: once by
the argument to the GPIO line itself where it was magically marked
as active low by the flag GPIO_ACTIVE_LOW (0x01) in the third cell,
and also marked active low AGAIN by explicitly stating
"cd-inverted" (a deprecated method).

After commit 78f87df2b4
"mmc: mmci: Use the common mmc DT parser" this results in the
line being inverted twice so it was effectively uninverted, while
the old code would not have this effect, instead disregarding the
flag on the GPIO line altogether, which is a bug. I admit the
semantics may be unclear but inverting twice is as good a
definition as any on how this should work.

So fix up the buggy device tree. Use proper #includes so the DTS
is clear and readable.

66e0c12f9e ARM: nomadik: switch to use the Nomadik I2C driver
Instead of using bit-banged I2C, let's use the actual I2C
driver in the kernel. Since the I2C block may be communicating
with things like the PMIC, we need to select it from the Kconfig
just like the bit-banged adapter is selected today. The rest of
the configuration for this driver can be done from the device
tree.

This revamps the device tree to fit with the new clock

After this the clock implementation knows about all
clock gates and will gate off all unused clocks at
boot time and save a bit of power.
