This converts all the 32-bit platforms to use the expanded device-tree
which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel
didn't rely on platform initializations to setup the MMU since it
sets it up entirely before probe_machine() so the move has comparatively
less consequences though it's a bigger patch.

of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime. All functions working with of_device_ids
provided by <linux/of.h> work with const of_device_ids. This allows to
mark all struct of_device_id const, too.
While touching these line also put the __init annotation at the right
position where necessary.

Add spi support for mgcoge into the platform code and the dts
file. Additionaly SPIDEV is switched on in the defconfig and the
updates for the newer kernel version are committed. The SPI
interface is used to drive the Maxim DS3106 clock chip.

The mgcoge board from keymile is now base for some other
similar boards. Therefore the board specific name mgcoge
was renamed to a generic name km82xx. Additionally some
enhancements were made:
- rework partition table in dts file
- add cpm2_pio_c gpio controller in dts file
- update defconfig
- add pin description for SCC1
- add pin description and configuration for USB
