This patch mimicks what Martin wrote on the mailing list:

* move arch/arm/mach-imx/include/mach/imxfb.h into
  arch/arm/mach-mxc/include/mach/imxfb.h
* changes Kconfig so that CONFIG_FB_IMX is selectable
* adds a platform device (copied from some pengutronix
  patches)

This changes MX27 to use common clkdev. It also cleans up MX27 clock
support to be more readable.

The context makes it clear already that these are clocks, so there's
no need for such a suffix. This patch only changes the clocks actually
used in the tree. The remaining clocks are renamed in the subsequent
architecture specific patches.

- rename mxc_clocks_init to architecture specific versions. This
  allows us to have more than one architecture compiled in.
- call mxc_timer_init from clock initialisation instead from board

We had 3 versions of this function in clock support for MX1/2/3
Use a single one instead. I picked the one from the MX3 as it seems
to calculate more accurate as the other ones. Also, on MX27 and MX31 mfn
can be negative, this hasn't been handled correctly on MX27 since now.

This patch has been tested on MX27 and MX31 and produces the same clock
frequencies for me.

mxc_gpio_setup_multiple_pins used to take several ALLOC_MODE flags. Most
of them are unused, so simplify the function by removing the flags. Also,
instead of using a confusing MXC_GPIO_ALLOC_MODE_RELEASE flag in a function
having alloc in its name, add a mxc_gpio_release_multiple_pins function.

This patch adds support for the phyCORE-i.MX27 cpu module (aka pcm038).
It is as generic as possible in order to support any kind of baseboard.

Note: This CPU module implementation can't work without a baseboard
support. Baseboard support can be added by the PCM-970 (included in
this patch stack) or any custom variant.

Internal clock path handling for the i.MX27 CPU.

Changed against the original Freescale code (and against clocklib for example):
 - clock rate is always calculated whenever one ask for the current rate.
   (means no "rate" member in the clock structure).
   So switching the PLL base frequency will propagate immediately to all
   other clocks that are depending on this frequency.

TODO:
 - Check if the i.MX21 CPU can share the same code.
