This patch adds board support for the Media5200 platform.  Changes are:
- add the media5200 device tree
- add the media5200 platform support code and cascaded interrupt controller
- add media5200 to the build targets.

Note: this patch also includes a minor tweak to the lite5200(b) target
images list to add the .dtb files to the image list.

This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression.  This
patch makes this easier by changing:
    bool "PCI support" if <long expression>
to
    bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.

Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but
it was removed in commit id 25431333
(bootwrapper: Build multiple cuImages).

This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs.

This patch adds support for 'mpc5200-simple-platform' compatible
boards which do not need a platform specific setup. Such boards
are supported assuming the following:

- GPIO pins are configured by the firmware,
- CDM configuration (clocking) is setup correctly by firmware,
- if the 'fsl,has-wdt' property is present in one of the
  gpt nodes, then it is safe to use such gpt to reset the board,
- PCI is supported if enabled in the kernel configuration
  and if there is a PCI bus node defined in the device tree.

This provides an implementation of the <linux/clk.h> interface for
arch/powerpc using a set of function pointers in clk_functions.
Platforms that want to support this interface should fill
clk_functions and select CONFIG_PPC_CLOCK in Kconfig.
