The merge commit "526b2641 Merge branch 'imx/cleanup' into imx/devel"
left a duplicated mx28_add_mxs_mmc() call, which causes the problem
below during boot.

  kobject_add_internal failed for mxs-mmc.1 with -EEXIST, don't try
  to register things with the same name in the same directory.

The patch removes this leftover and also change mmc0 adding to align
with mmc1.

Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to
reset the clock divider for the SSP0 parent clock, in this case
IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but
when the new frac value is written the value isn't shifted up to write
the correct bit-field.  This results in IO0FRAC being set to 0 and
CPUFRAC being corrupted.

This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0
and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1.

Tested on custom i.MX28 board with SSP0 SPI driver.

Boards used to specify zreladdr in their Makefile.boot with
zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
This patch changes this to zreladdr-y += x, so that we end
up with multiple words in zreladdr in such a case. We can
detect this later and complain if necessary.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

Now most of ARM machines has the alsmot same __clk_get/put() macro

So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files

But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config

Now there are only 3 caese.

1) define the clk structure with clkdev macro => Need to move clk structure to proper header file

arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h

2) export the __clk_get/put function at clock.c

arch/arm/mach-shmobile/include/mach/clkdev.h

3) demuxing the clk source

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

The patch makes necessary changes on gpio-mxs as below to turn it
into an upstanding gpio driver.

 * Clean up the gpio port definition stuff

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxs_gpio_init into mxs_gpio_probe function

And it then migrates mach-mxs to the updated driver by adding
corresponding platform devices.
