There's no need to keep the device related things in the
common i2c.c as omap2+ is using hwmod. Split the code to
mach-omap1 and mach-omap2 parts and only leave common
code to plat-omap/i2c.c.
Note that as omap1 only has one i2c controller, we can
now remove the old device related macros.

There's no need to have this file in plat/fpga.h. We can
make it local to plat-omap replacing fpga_read/write
functions directly with readb/writeb as that's how
they are already defined in fpga.h.
Note that 2420 based H4 is also using the fpga, so let's
keep the led support around in plat-omap until we flip
over mach-omap2 to device tree.

This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.
The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.
The vrfb driver will parse those resources and use them to access vrfb
configuration registers and the vrfb virtual rotation areas.

Add new enum, omapdss_version, that is used to tell which DSS hardware
version the SoC has. This enum is initialized during platform init, and
passed in the platform data to omapdss driver.
Note that the versions are not "continuous", that is, you cannot check
if the version is less or greater than something, but you need to check
for exact version match. In other words, this is invalid:
/* test if DSS is 3630 or earlier */
if (ver <= OMAPDSS_VER_OMAP3630)

Drivers should not use cpu_is_omap or cpu_class_is_omap macros,
they should be private to the platform init code. And we'll be
removing plat/cpu.h and only have a private soc.h for the
arch/arm/*omap* code.
This patch is intended as preparation for the core omap changes
and removes the need to include plat/cpu.h from several drivers.
This is needed for the ARM common zImage support.
These changes are OK to do because:
- omap-rng.c does not need plat/cpu.h
- omap-aes.c and omap-sham.c get the proper platform_data
passed to them so they don't need extra checks in the driver
- omap-dma.c and omap-pcm.c can test the arch locally as
omap1 and omap2 cannot be compiled together because of
conflicting compiler flags

A platform function pointer for getting the frequency of a OneNAND device
was added so that a platform could specify a custom function for returning
the frequency and not just rely on the OneNAND version to determine the
frequency. However, this platform function pointer is not currently being
used and I am not sure if it ever has.
OneNAND devices are not so common these days and as far as I know not being
used with new devices. Therefore, it is most likely that this get_freq()
function pointer will not be used and so remove it.
Given that the get_freq() function pointer is not used, neither is the
clk_dep variable and so all references to it can also be removed.
